Background Art

Generally speaking, compressor is from such as electric motor, turbine or the like and obtain power to the power equipment for compressed air, refrigerant or other various working gas in order to increase the pressure of the mechanical equipment. The compressor has been widely used, for example, household appliances such as refrigerator and the air conditioner or is widely used in industry as a whole.

Compressor generally divided into: a reciprocating compressor, the between the piston and the cylinder defining a compression chamber, the working gas is drawn into the compression chamber and discharged from the compression chamber, and refrigerant with the extension of the piston in the cylinder is compressed by the reciprocating motion manner; the rotary compressor, defined in the eccentric rotation of the drum and a cylinder between the compression working gas compression chamber; and a scroll compressor, the fixed scroll and orbiting scroll defining a compression chamber between the, working gas is drawn into the compression chamber and discharged from the compression chamber, and refrigerant as the orbiting scroll is rotated along the fixed scroll is compressed.

Although reciprocating compressor is more excellent in the mechanical efficiency, but its reciprocating movement causing serious vibration and noise problems. In view of this problem, the rotary compressor of the compact size and has excellent vibration characteristics and can be developed.

The rotary compressor to be constructed in the following manner: the motor and the compression mechanism part is installed in the hermetic container of (hermetic   container) on the driving shaft, around the drive shaft with the eccentric part of the drum is set up in a cylinder, the cylinder having a cylindrical compression chamber, and at least one vane extending between the cylinder and the compression chamber, the compression chamber is divided into a suction area and a compression area, and the roller is eccentrically arranged in the compression chamber. Usually, the blades of the cylinder the recess in the spring support, in order to exert pressure on the ground surface of the cylinder, and the above-mentioned (a plurality of) vane of a compression chamber is divided into a suction area and a compression area. Usually, the blades in the cylinder of the spring support, in the surface pressure of the cylinder, and as mentioned above, (a plurality of) vane of a compression chamber is divided into a suction area and a compression area. The rotation of the drive shaft with the suction zone of gradually expanding, in order to suck the refrigerant or working fluid wherein a compression area is gradually retracted at the same time to compress the refrigerant or working fluid.

In this conventional rotary compressor, in the eccentric portion of the drive shaft during rotation of the drum the fixed cylinder is fixed to the inner surface of the fixed drum of the same and the tip of the blade continuously both sliding contact. In sliding contact with each other is generated between the component elements of the relative speed is high, the friction loss produced by this, ultimately lead to reduced efficiency of the compressor. And, between the blades and the roller at the contact surface of the refrigerant leakage may still occur, thus leading to reduced mechanical reliability.

fixed cylinder the conventional object is different is the rotary compressor, the United States Patent section 7,344,367, discloses a rotary compressor, it has provided in the rotor and is rotatably mounted on the stationary shaft between the discharge chamber of the cylinder. In this Patent, the fixed shaft extending longitudinally inwardly in the shell, electric machine comprises a stator and a rotor, the rotor is rotatably mounted within the housing of the fixed shaft, the roller is rotatably mounted in the integrally formed with the stationary shaft on the eccentric part of the. Furthermore, the blade is inserted between the rotor and the cylinder, in order to make the drum with the rotating together with the rotation of the rotor, so that the compressed working fluid of the compression chamber. However, even in the Patent, with the fixed shaft in sliding contact with the inner surface of the drum, thus generated between the two higher relative speed, this Patent still has the conventional rotary compressor the problems in the.

At the same time, Patent Bulletin WO2008/004983 disclosed another kind of rotary compressor, which comprises: the cylinder; the rotor, is mounted in the cylinder, eccentric rotation relative to the cylinder; and the vane, is located in the rotor is in the slot of the, blades relative to the rotor sliding, wherein the blade is connected to the cylinder in order to force is transmitted to the with the rotation of the rotor to rotate together with the cylinder, and wherein the defined in the cylinder and the rotor between the compression chambers of the compression a working fluid. However, because the rotor is transmitted through the driving shaft of the driving force to rotate, therefore, this type of rotary compressor need for separate electric motor to drive the rotor. That is to say, when the implement according to the disclosed content of the rotary compressor, a separate motor on the stacking by the rotor, cylinder and blades of a compression mechanism part in the height direction, so that the total height of the compressor inevitably increases, making it difficult to realize the compact design.

Mode of execution

In the below, will combine with photos detailed description of the preferred embodiment of the present invention.

Figure 1 is an exploded perspective view of according to the present invention is shown of the embodiment of the 1st-sectional diagram of the compressor, Figure 2 is shown according to the present invention of the embodiment of the 2nd-sectional diagram of the compressor, Figure 3 is shown according to one embodiment of the present invention the electric motor of the compressor of an example of an exploded perspective view, and Figure 4 and Figure 5 show the respective draws shows according to one embodiment of the present invention part of the compression mechanism of the compressor an example.

As shown in Figure 1, according to the invention, the 1st and 2nd embodiment of the compressor comprises: a sealed container 110 ; the stator 120, is mounted in the hermetic container 110 inner; 1st rotation member 130, is mounted in the stator 120 and by means of the from the stator 120 and the rotating electromagnetic field; 2nd rotation member 140, by means of the same from the 1st rotation member 130, and 1st transfer the rotation force of the rotation member 130 is rotated in the, rotary member for compressing is in the 1st and 2nd refrigerant between the rotary component; and 1st support member 150 and 2nd support member 160, its support 1st rotation member 130 and 2nd rotation member 140, so that it can in the hermetic container 110 to rotate within. Through the electrical reaction (  reaction electrical) electric mechanism components provide power using, for example, includes a stator 120 and 1st rotation member 130 of the BLDC motor, compressed refrigerant through the mechanical response of a compression mechanism part includes the 1st rotation member 130 and 2nd rotation member 140 and 1st support member 150 and 2nd support member 160. Therefore, through the radially arranged with an electric mechanism part and the compression mechanism part, the total height of the compressor can be reduced. Although the embodiment of the invention described the compression mechanism part is disposed in the electric motor part of the so-called inner rotor type as an example, however one of ordinary skill in the art it should be easy to understand that, the above-mentioned general concept also can be conveniently applied to the compression mechanism part is disposed outside of the electric mechanism part of the so-called outer rotor type.

As shown in Figure 1, a sealed container 110 by the cylindrical main body 111 and the upper housing 112 and lower housing 113 composition, and detecting the height of the storage a suitable lubricating or smooth 1st to the rotation member 130 and 2nd rotation member 140 (see fig. 1), the upper housing 112 and lower housing 113 is coupled to the main body 110 at the top and bottom. Upper housing 112 includes in a predetermined position for suction of the refrigerant of the suction tube 114 and in another predetermined position for discharging refrigerant of the discharge line 115. Here, compressor is high-pressure compressor or a low-pressure compressor depends on the sealed container 110 is filled with the inside of the refrigerant after compression or compression of the refrigerant, and should be determined based on the suction tube 114 and the discharge pipe 115 position.

With reference to Figure 1, 1st embodiment of the present invention on the low-pressure compressor. For this purpose, the suction tube 114 is connected to the sealed container 110, the discharge pipe 115 is connected to the compression mechanism part. Therefore, when the low-pressure refrigerant through the suction tube 114 is absorbed, the refrigerant is filled in the sealed container 110 and flows into the inside of the compression mechanism part. In the compression mechanism part, the low-pressure refrigerant is compressed to high pressure and then directly through the discharge pipe 115 discharge. On the other hand, Figure 2 shown in a 2nd embodiment of the present invention is the high-pressure compressor, wherein the suction pipe the 114 [...] passes through the sealed container 110 is directly connected to the compression mechanism part. From the compressing mechanism part of the compressed refrigerant is discharged into the sealed container 110 internal, therefore the container 110 is filled with the inside of the high-pressure refrigerant. Sealed container 110 through the discharge line of a high-pressure refrigerant within the 115 [...] is discharged, the discharge pipe 115 the one end of the [...] crosses the sealed container 110 in the container in order to set up the 110 inner. The first high-pressure refrigerant discharged into the sealed container 110 and through the discharge line after 115 the discharged [...] , therefore, compared with the structure of the low-pressure compressor, the structure of the high-pressure compressor may be subjected to some compression loss, however, can reduce the pulsation of the refrigerant, and produces smaller than the noise of the low pressure compressor. At the same time, also can construct such a compressor, it does not have a sealed container 110, and a suction tube 114,114 the discharge pipe and [...] the 115,115 [...] can be inserted into to the compression mechanism part in order to make the refrigerant directly into the compression mechanism section and discharged from the compression mechanism part. However, in this case, preferably in the compressor installation at the same time of mounting the receiver in order to separate the liquid refrigerant, and the refrigerant in a stable manner to the compression mechanism part.

As shown in Figure 3, stator 120 by the magnetic core 121 and substantially around the core 121 wound coils 122 composition. Although conventional BLDC motor is used as the magnetic core along the peripheral has 9 slots, but because this invention in the preferred embodiment the diameter of the stator has a relatively large, the magnetic core of the BLDC motor 121 has along the periphery of the 12 grooves. Taking into account the coil along with the increase in the number of magnetic core troughcircles the number increase, in order to produce the conventional stator 120 electromagnetic force, the core 121 can be provided having a relatively small height.

As previously mentioned, roller 142 the suction passage 142a (see Figure 1) is located in suction area S, and 1st end cap 133 (see Figure 1) the discharge port 133a (see Figure 1) is located in discharge area D, drum 142 the suction passage 142a (see Figure 1) and 1st end cap 133 (see Figure 1) the discharge port 133a (see Figure 1) is arranged with the adjacent blade 143 discharge inclined portion 136 is connected. Therefore, in the conventional rotary compressor and the cylinder or the cylinder is separately fabricated and supported by the springs compared with the blade, in the compressor of this invention with the roller 142 for the integral production and assembled to the bushing 144 is slidably moveable between the blade 143 can reduce the friction loss caused by the contact of the slide, and can reduce the suction zone and the discharge zone between D S the refrigerant leakage.

At this moment, a cylindrical rotor 131 and the cylinder 132 is transmitted to the rotation of the rotation member formed in the 2nd 140 the blades 143 in order to make the rotation of the rotation member, and inserted into the blade mounting slot 132h of the bushing 144 to swing, whereby the cylinder-shaped rotor 131, cylinder 132 and 2nd rotation member 140 can rotate together. Air cylinder 132 and the cylinder 142 is rotated, blade 143 relative to the cylinder 132 of the blade mounting slot 132h relatively linear reciprocating motion.

Therefore, when the rotor 131 is because the stator 120 (see Figure 1) of the rotating electromagnetic field generated by the the action of rotating force, the rotor 131 and the cylinder 132 to rotate. Because the blade 143 is inserted into the cylinder 132 in, the rotor 131 and the cylinder 132 of the rotary force is transmitted to the drum 142. With the rotation of the two, blade 143 that is, the bushing 144 linearly reciprocating movement between. That is to say, the rotor 131 and the cylinder 132 with the each roller 142 of the outer surface of the inner surface of the face, and these corresponding to the portion along with the rotor 131/cylinder 132 and the cylinder 142 and of each other each time the repeated contact and separation. In this case, one expands gradually S, refrigerant or working fluid is sucked to the suction area S, at the same time discharge gradually D shrink in order to make the refrigerant or working fluid is compressed therein and then is discharged.

Part by a compression mechanism, the suction, compression and discharge operation of the circulating how, Figure 6a shows a refrigerant or working fluid will be sucked into the suction zone of the steps in S. For example, a working fluid is sucked and then compressed in D in the discharge zone. When the 1st rotation member 130 and 2nd rotation member 140 as shown in Figure 6b shows is set the, working fluid is continuously sucked and S corresponding one to perform compression. When the 1st rotation member 130 and 2nd rotation member 140 as shown in Figure 6c shows is set the, working fluid is continuously sucked, and discharge zone in D with the preset pressure or more high-pressure refrigerant or working fluid through discharge inclined portions (or discharge port) 136 is discharged. Finally, when the 1st rotation member 130 and 2nd rotation member 140 as shown in Figure 6d is set as shown, the compression of the working fluid and a discharge end. In this way, the compressing mechanism part of a cycle is complete.

Figure 7 is an exploded perspective view of the compressor according to the present invention is shown of one example of the support element.

As shown in Figure 1 when the compressor is a low-voltage system, suction guide channel 151 and the sealing container 110 is communicated with the interior of, the through the suction tube 114 is of the refrigerant sucked into the sealed container 110 ; as shown in Figure 2 when the compressor is the high-pressure system, the suction tube 114 the insert a portion of [...] to the suction guiding passage 151 in. Furthermore, bearing member 1st 150 includes discharging the guide channel 152, the discharge guide channel 152 and the 1st end cap 133 discharge port 133a is connected with, the discharging port 133a in the form of a ring or loop, in order to accommodate the end cover 1st 133 discharge port 133a rotating track, so that even in the 1st end cap 133 discharge port 133a is rotated, also can be through the 1st end cap 133 discharge port 133a via the refrigerant flowing out of the discharge line 115 discharge. In as shown in Figure 7 under the condition of the low-pressure compressor, the discharge guide channel 152 includes a discharge pipe mounting hole 153, discharge guide channel 152 to the mounting hole through the discharge pipe 153 is directly connected to the discharge line 115, the refrigerant is directly discharged to the outside; in as shown in Figure 8 the case of the high-pressure compressor, the discharge guide channel 152 includes 1st support member 150 of the discharge port the 153 [...] , is used for the refrigerant into the sealed container 110 inner. Through the discharge port the 153 [...] above the high-pressure refrigerant is discharged via the discharge line of the pointed out that by the 115 [...] leave the sealed container 110.

2nd support member 160 is configured to adopt the journal bearing rotatably supporting the rotating shaft to the 141 and 2nd the outer peripheral surface of the end cap 134 and the inner peripheral surface of the, and by thrust bearings for rotatably supporting the cylinder 142 and 2nd the lower surface of the end cap 134 of the lower surface. 2nd support member 160 to the lower shell by the opening 113 of the flat support member (support) 161 and which is arranged in the supporting plate 161 central shaft 162 composition, on the shaft has projecting from the hollow part (hollow) 162a. At this moment, 2nd support member 160 of the hollow part 162a formed in the center of the support member with respect to the 2nd 160 of the shaft 162 of the center of the eccentric position, and the 2nd support member 160 of the shaft 162 with the 1st the center of the rotation member 130 with the rotary center line of the line, at the same time support 2nd 160 the hollow section 162a and 2nd the center of the rotation member 140 of the rotary shaft 141 co-linear. That is to say, while the 2nd rotation member 140 of the rotary shaft 141 with respect to the 1st the center line of the rotation member 130 is formed eccentrically with the rotary center line of the, but can also be along the drum 142 is formed concentrically of the longitudinal centerline. Will now provide more detail below.

Fig. 9 to fig. 11 showing the respective the draws shows according to an embodiment of the invention with the rotary center line of the compressor of Figure of the cross section.

In order to make the 1st rotation member 130 and 2nd rotation member 140 can compress refrigerant when rotating, 2nd rotation member 140 with respect to the 1st rotation member 130 is eccentrically positioning.

In the Figure, "a" said rotation member 1st 130 of the center line of the shaft 1st, 2nd end cover or 134 shaft 134b or longitudinal center line of the supporting member 160 of the shaft 162 of the longitudinal centerline. Here, because the 1st rotation member 130 comprises a rotor 131, cylinder 132, 1st end cap 133 and 2nd end cap 134, as shown in Figure 4, all of the components as a whole to rotate together, so that it is considered that "a" is that they with the rotary center line of the, said "b" 2nd rotation member 140 of the center line of the rotating shaft or rotating shaft 2nd 141 of the longitudinal centerline, said "c" and 2nd rotation member 140 or longitudinal center line of the drum 142 of the longitudinal centerline.

As regards fig. 1 to fig. 6 show embodiments of the present invention, Figure 9 shows the center line of the rotating shaft the 2nd and 1st "b" "a" the center line of the rotating shaft are spaced apart by a predetermined distance, and 2nd rotation member 140 "c" of the longitudinal centerline of the center line of the rotating shaft with the 2nd "b" line. In this way, 2nd rotation member 140 with respect to the 1st rotation member 130 is eccentrically disposed, and when the 1st rotation member 130 and 2nd rotation member 140 by means of a blade 143 is rotated together with the intermediary of the role, they, like the previous indicated in each rotation repeatedly in contact, separation and re-touch (retouch), thereby changing the suction zone of the volume of the D S/discharge, in order to compress refrigerant in the compression chamber P.

Figure 10 shows the center line of the rotating shaft the 2nd and 1st "b" the center line of the rotating shaft are spaced apart by a predetermined distance "a", 2nd rotation member 140 "c" of the longitudinal centerline of the center line of the rotating shaft with the 2nd are spaced apart by a predetermined distance "b", but the center line of the shaft 1st and 2nd "a" rotation member 140 of the longitudinal centerline "c" is not co-linear. Similarly, 2nd rotation member 140 with respect to the 1st rotation member 130 is eccentrically disposed, and when the 1st rotation member 130 and 2nd rotation member 140 by means of a blade 143 is rotated together with the intermediary of the role, they, like the previous indicated in each rotation repeatedly in contact, separation and re-touch, thereby changing the suction zone of the volume of the D S/discharge, in order to compress refrigerant in the compression chamber P. In this way, can provide compared to chart 9 greater eccentricity.

Figure 11 shows the center line of the rotating shaft 2nd and 1st "b" the center line of the axis of rotation "a" co-linear, 2nd rotation member 140 "c" of the longitudinal centerline of the central line of the shaft 1st and 2nd "a" "b" the center line of the rotating shaft both of which are spaced apart by a predetermined distance. Similarly, 2nd rotation member 140 with respect to the 1st rotation member 130 is eccentrically disposed, and when the 1st rotation member 130 and 2nd rotation member 140 by means of a blade 143 is rotated together with the intermediary of the role, they, like the previous indicated in each rotation repeatedly in contact, separation and re-touch, thereby changing the suction zone of the volume of the D S/discharge, in order to compress refrigerant in the compression chamber P.

Figure 12 is an exploded perspective view of according to the present invention shows a 1st/2nd embodiment of the compressor.

By reference to the Figure 1 and Figure 12 according to the present invention to understand the 1st/2nd how to assemble the embodiment of the example of the compressor, the rotor 131 and the cylinder 132 or separately manufactured and then connected together, or from the beginning of manufacturing into a unit. Rotating shaft 141, the roller 142 and the vane 143 can also be separated or made integrally, but the manufacturing method used, they should be able to rotate as a unit. The blade 143 is inserted into the cylinder 132 of the bushing 144 between. In general, shaft 141, the roller 142 and the vane 143 is installed in the rotor 131 and the cylinder 132 the inner. 1st end cap 133 and 2nd end cap 134 is along the rotor 131 and the cylinder 132 jiukong in the axial direction, even if the rotary shaft 141 may be in the rotor 131 and the cylinder 132 through the between, end cover will also cover the drum 142.

With the 1st rotation member 130 and 2nd rotation member 140 rotating component after assembly mounted together after such as mentioned above, the 2nd support member 160 to the lower shell opening 113, then the rotary component is assembled to the 2nd support member 160, and the 2nd end cap 134 shaft 134b and the inner peripheral surface of the shaft 162 is connected to the outer peripheral surface of, the shaft 141 with the 2nd the outer peripheral surface of the supporting member 160 of the hollow part 162a endo. Next, the stator 120 press-fit to the body 111 in, the main body 111 is coupled to the upper shell 112, the stator 120 is positioned to the outer peripheral surface of the rotary assembly and to maintain an air gap. Thereafter, through the upper casing 112 the discharge line 115 is press fitted into the mounting hole of the bearing member 1st discharge 153 (see Figure 6) of the bearing member 1st 150 is connected to the upper shell or assembly 112. In this way, the bearing member 1st 150 the upper casing after assembly 112 is coupled to the main body 111, at the same time, the rotary shaft 141 and 1st end cap 133 of bearing member 1st between 150 the shell 112 is covered from above. There is no need to specify is, bearing member 1st 150 suction guide channel 151 and the rotary shaft 141 the suction passage 141a communicating, bearing member 1st 150 of the discharge guide channel 152 and the 1st end cap 133 discharge port 133a is connected with.

Therefore, the assembling with the 1st rotation member 130 and 2nd rotation member 140 of the rotary assembly, is provided with a stator 120 of the body 111, is provided with a 1st support member 150 of the upper housing 112 and is provided with a 2nd support member 160 of the lower housing 113 is connected with all of the axial direction, bearing member 1st 150 and 2nd support member 160 along the axial direction of the rotary assembly is rotatably supported in the sealed container 110 on.

Figure 13 is cross-sectional view of shows according to the invention, the 1st/2nd in the compressor of the embodiment of the flow of refrigerant and oil.

By reference to the Figure 1 and Figure 13 to understanding of the compressor of the present invention of how 1st/2nd operation condition of the embodiment, when the to the stator 120 when the power is supplied, the stator 120 and the rotor 131 is generated between the rotating electromagnetic field, and the from the rotor 131 of the rotation force, so that the 1st rotation member 130, that is, the rotor 131 and the cylinder 132 and 1st end cap 133 and 2nd end cap 134 as a unit and rotate together. Because blade 143 is mounted in the cylinder 132 in order to be able to the linear reciprocating motion, 1st rotation member 130 is transmitted to the 2nd rotary force of the rotary member 140, thus 2nd rotation member 140 (that is, shaft 141, the roller 142 and the vane 143) as a unit and rotate together. As shown in fig. 9 to fig. 11 as shown, because the 1st rotation member 130 and 2nd rotation member 140 is eccentrically disposed relative to each other, they rotate repeatedly in every time contact, separation and re-touch, thereby changing the suction zone of the volume of the D S/discharge, in order to compress refrigerant in the compression chamber P, and at the same time pumping oil, is used for the two sliding contact between the components to lubricate.

When the 1st rotation member 130 and 2nd rotation member 140 rotates, the refrigerant is sucked, compressed and discharged. At a more detailed level, drum 142 and the cylinder 132 between the compression chamber P defined by the roller 142 and the cylinder 132 and the contact part between the blade 143 is divided into a suction area and the discharge area. Drum 142 and the cylinder 132 with the contact part between the 1st rotation member 130 and 2nd rotation member 140 but continuous change of rotation of, and each time the touch a time in the rotation. In accordance with the drum 142 and the cylinder 132 between the change of the contact part, the volume and the suction zone of the change of the volume of the discharge region, with the suction, compression and discharge of the refrigerant. When the discharge valve (not shown) in excess of a preset level when opened under the pressure of, the refrigerant begins to discharge from the discharge region, the discharge process continues to the cylinder 142 and the cylinder 132 with the contact part between the discharge port of the cylinder 136 until the overlap. At the same time, sometimes the roller 142 and the cylinder 132 the position of the contact part between the blade 143 overlap the position of, the suction area and the discharge area of the divided dematerialised, and the whole of the compression chamber into a region P-shaped. However, immediately after that, the roller 142 and the cylinder 132 between the position and the contact part of the blade 143 of the 1st position of the rotation member 130 and 2nd rotation member 140 is changed by the rotation of the, compression chamber P is once again divided into volume expansion and volume contraction of the one discharge zone S D. In earlier in the rotation of the of the refrigerant sucked through the suction zone of the rotation of the then compressed in the discharge zone. The position of the refrigerant from the suction zone to the discharge zone changes the time and the drum 142 and the cylinder 132 the position of the contact part between the blade 143 about the position of the same overlapping period of time.

In other words, because of the gradually increasing the volume of the suction zone of the produced in the suction zone of the suction pressure (negative pressure), the refrigerant through bearing member 1st 150 suction guide channel 151, rotating shaft 141 the suction passage 141a and the roller 142 the suction passage 142a is sucked into the suction zone of the compression chamber P. And, is gradually reduced as the volume of the discharge region, in which the refrigerant is compressed, and when the discharge valve (not shown) in excess of a preset level when opened under the pressure of, the refrigerant after compressing through the cylinder 132 of the discharge port 136, the discharge port end cover 1st 133a and 1st support member 150 of the discharge guide channel 152 discharge the sealed container 110 outside. According to the 1st bearing 150 suction guide channel 151 used for the low pressure refrigerant and from the structure of the channel of bearing member 1st 150 of the discharge guide channel 152 of the high pressure refrigerant discharged by the structure of the channel for, the compressor can be classified as high-pressure compressor or a low-pressure compressor. If the compressor is based on the Figure 1 construction of a low-voltage system shown, low pressure refrigerant through the suction tube 114 from being sucked into the sealed container 110 in, and the sealing container 110 the inside of the suction guiding passage 151 is connected with, and the high-pressure of the refrigerant after compression by the insertion of the discharge guide channel 152 in the discharge line 115 directly discharged. On the other hand, if the compressor is based on the Figure 2 construction of the high-pressure system shown, is inserted into the low-pressure refrigerant through the suction guide channel 151 of the suction tube 114 the inhaled [...] , and the high-pressure of the refrigerant after compression is discharged through a guide channel 152 on one end of the discharge port the 153 [...] (see Figure 8) is discharged into the sealed container 110 inner, then through discharge line 115 the final [...] is discharged into the sealed container 110 outside. Inductions speaking, for low-voltage system, refrigerant through the suction tube 114, sealed container 110 internal, bearing member 1st 150 suction guide channel 151, rotating shaft 141 the suction passage 141a and the roller 142 the suction passage 142a from being sucked into the compression chamber P, in a rotating and enters into the discharge zone, and the volume of the compression area is compressed by the decrease of the, if the discharge valve (not shown) in excess of a preset level to open under the pressure of, the refrigerant goes through the cylinder 132 of the discharge port 136, 1st end cap 133 discharge port 133a, bearing member 1st 150 of the discharge guide channel 152 and the discharge pipe 115 discharged into the sealed container 110 outer. At the same time, the high-pressure system, the refrigerant goes through the suction pipe the 114 [...] , bearing member 1st 150 suction guide channel 151, rotating shaft 141 the suction passage 141a and the roller 142 the suction passage 142a from being sucked into the compression chamber P, in a rotating and enters into the discharge zone, with the compression area is compressed by the decrease of the volume, and if the discharge valve (not shown) in excess of a preset level to open under the pressure of, the refrigerant goes through the cylinder 132 of the discharge port 136, 1st end cap 133 discharge port 133a, bearing member 1st 150 of the discharge guide channel 152 and the discharge pipe 115 the is discharged to the sealed container [...] 110 outside.

The volume of the discharge zone and the suction zone of the change is because the roller 142 and the cylinder 132 and the contact part between the blade 143 of the relative positioning of the position of the difference, the suction passage of the cylinder 142a and the cylinder 132 of the discharge port 136 must be relative to the blade 143 is arranged opposite to each other. Furthermore, assuming that 1st rotation member 130 and 2nd rotation member 140 to rotate in a counter clockwise direction. Then the drum 142 and the cylinder 132 with respect to the contact part between the blade 143 transfer along a clockwise direction. Therefore, in the direction of rotation, cylinder 132 the discharge port 136 should be positioned in the blade 143 of the front side of the, drum 142 the suction passage 142a should be positioned in the blade 143 of the more rear side. At the same time, drum 142 the suction passage 142a and the cylinder 132 of the discharge port 136 should be formed to be as close as possible to the blade 143, in order to reduce the actual compression of the refrigerant does not expand or shrink the purposes of the dead volume of the compression chamber P (dead   volumn).

Furthermore, the 1st rotation member 130 and 2nd rotation member 140 during rotation, oil is supplied to the bearing 150,160 and 1st the rotation member 130, 2nd rotation member 140 of the sliding contact part between, or is supplied to the 1st rotation member 130 and the 2nd rotary member 140 of the sliding contact part between, so that the lubrication between these components. For this purpose, rotating shaft 141 immersed in the stored in the sealed container 110 of the oil in the lower region of the, and 2nd rotation member 140 is used for oil supply to the oil passage of any kind. The purposes of a more detailed, when the rotary shaft 141 in stored in the sealed container 110 in the lower region of the rotation of the oil, along the axis of the helical member 145 or is arranged on a rotating shaft 141 of the oil feeder 141b the slot in the pumping or to increase, and by the rotating shaft 141 of the oil hole 141c from escaping, in order to make it not only is collected to the rotating shaft 141 and the 2nd support member 160 oil between 141d, but also on the shaft 141, cylinder 142, 2nd support member 160 and 2nd end cap 134 to lubricate between. Has been collected in the rotating shaft 141 and the 2nd support member 160 oil between 141d of the drum 142 to the oil hole 142b pumping or to increase, so that the oil is not only collecting to the rotating shaft 141, cylinder 142 and 1st support member 150 between the oil storage tank of 141e, 142c, and in rotating shaft 141, cylinder 142, 1st support member 150 and the 1st end cap 133 to lubricate between. Moreover, oil can also be through the oil groove or oil hole on the blade 143 and the bush 144 is supplied between, but the better one is the bushing 144 is made of self-lubricating material.

As has been explained so far, since the refrigerant from being sucked into the rotary shaft 141 the suction passage 141a, of oil through the rotating shaft 141 of the oil feeder 141b pumping, therefore, in rotating shaft 141 of the refrigerant circulation passage is separated from the oil circulation passage, so that the refrigerant is mixed with the oil will not occur. Furthermore, reduced oil leakage of the refrigerant and, in order to ensure that the working reliability of the entire compressor.

Now referring to the attached drawing and the embodiment of the present invention are described in detail. However, the scope of, the invention is not limited to these embodiments and drawings, but is attached to the right from such as defined by the claims.
