본 발명은 가스나 공기등과 같은 압축성 유체나 물이나 기름등과 같은 비압축성 유체등을 압축 이송토록 하는 압축기에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compressor for compressing and conveying a compressive fluid such as gas or air or an incompressible fluid such as water or oil. 종래 피스톤식 압축기는 회전력을 직선운동으로 변환시키는 힘 전달장치 등에서 소비되는 동력낭비가 많게 되며, 소음 및 진동이 많이 발생되며, 압축효율이 낮은 것을 볼 수 있다. Conventional piston compressor has a lot of power wasted in the force transmission device for converting the rotational force into a linear motion, a lot of noise and vibration is generated, it can be seen that the compression efficiency is low. 또한, 최근 개발된 스크롤 압축기는 왕복동 압축기에 비해 효율이 높으며, 진동 및 소음이 적으며, 소형, 경량화가 가능하나 고도의 정밀성을 요구하며, 복잡한 구조를 가지며, 고압의 용도에는 부적하며, 비압축성 유체를 압축매질로 사용하는 것은 부적절한 것을 볼 수 있다. In addition, recently developed scroll compressors have higher efficiency, less vibration and noise, smaller size and lighter weight than reciprocating compressors, but require a high degree of precision, have a complex structure, and are not suitable for high pressure applications. It can be seen that it is inappropriate to use as a compression medium. 본 발명은 왕복식 압축기와 같이 소음 및 진동이 많이 발생되지 않으며, 고압의 압축비율을 얻을 수 있도록 한 것으로, 원통형 실린더로 구성되는 본체에 유입구와 배출구를 가지며, 본체 내측의 원통형 압축실에 편심되게 회전축 및 로타를 설치하며, 원통형 압축실에 편심되게 설치되는 로타에 그 중심을 관통하는 끼움홈을 형성하고, 이에 2개로 분리되는 회전가압편을 원통형 압축실 내주면에 당접되게 하며, 로타의 표면에 원통형 압축실 내주면에 당접되는 가압핀을 형성토록 한 것으로, 원통형 압축실에 편심되게 설치되는 로타가 회전될 때 이에 결합된 회전가압편이 원통형 압축실 내주면을 당접되어 회전되면서 회전가압편은 원통형 압축실 내로 유입된 유체를 가압 압축토록 하는 압축기에 관한 것이다. The present invention is not to generate a lot of noise and vibration, such as a reciprocating compressor, to obtain a high compression ratio, having an inlet and an outlet in the body consisting of a cylindrical cylinder, eccentric in the cylindrical compression chamber inside the body The rotary shaft and the rotor are installed, and the fitting groove penetrating the center is formed in the rotor installed eccentrically in the cylindrical compression chamber, and the ...

Eccentric rotary piston engine with radial sealing strips - has ports controlled by lobes moving in recesses in the housing

The rotary piston engine comprises a housing with concentric shaft which carries an eccentric rotor with radial sealing strips, and means to control inlet and outlet of the working medium. The rotor carries out a precession movement without itself rotating, under the control of lobes (12) which move through recesses (13) in the housing thereby controlling inlet and outlet ports (18, 19). The lobes (12) may be radial projections of a disc (14) moving with the rotor, and there may be four such projections moving in corresponding housing recesses (13) of part-circular contour whose radius corresponds with the eccentricity of the rotor. The disc (14) may be arranged at one end face of the rotor.

Compressor for air conditioning

The air conditioning compressor has a casing (12) with two compressor assemblies in respective discharge chambers (32,36). The main bearing plates (20,22) of the compressors are spaced to divide the casing into the discharge chambers and a suction chamber (44) between the main vanes. The suction chamber receives the drive motor.

Hydraulic motor with oval rotor in circular cylinder - has throttling passages between high and low pressure sides

The motor has a circular cylinder within which is a rotor which has opposed ends on a major diameter and sections between them of a smaller diameter. The cylinder has inlet and discharge passages leading from inlet and discharge ports. The gap between the reduced diameter of the rotor and the cylinder forms the working chambers. The cylinder contains two spring loaded plungers which press on the rotor and form a seal between the high and low pressure sides. Deepened grooves in the cylinder between the inlet and discharge passages allow a small leakage from one side to the other and reduce the suddenness of the pressure change as the fluid passes from one side to the other.

Rotary-piston electrohydraulic brake or motor - has sliding magnetic rotor blades bearing on deformable cycloidal stator surface

The intermediate space between the rotor (1) and stator (2) is circularly variable in the axial direction and is defined in part by a continuous stator base surface (6) of constant width. Blades (5) sliding axially on the rotor bear wholly and in a constant manner on the stator base (6) which is unique for a specific set of blades and pref. cycloidal. The magnetic field is created by one or more coils (7) and the blades (5) may be retained in their cavity by a permanent magnet (8). The stator surface is deformable so as to make rectilinear zones or spaces suited to the required function of the device.. The arrangement is applicable to electrohydraulic braking or decelerating systems, volumetric pumps or motors.

BLADE FOR ROTARY COMPRESSOR

Volumetric machine with vanes

The volumetric machine with vanes, which can operate as a pump or as a compressor, comprises a stator ring delimited internally by its stator surface 102, a rotor 108 rotating about its axis inside this ring, inlet and exhaust devices, and vanes 110 sliding in grooves 109 of the rotor 108. Any contact U of each vane 110 with the rotor 108 is located outside the space lying between the lines 112 and 113 of the planes bounding the guide groove 109 of the vane 110 in the rotor 108 and in front of this space, in the direction of the movement of the rotor, at least for all angular positions of the vane which correspond to the decrease in volume of the working chamber located in front 116 of this vane 110.

Rotary compressor for air conditioner

The rotary compressor (10) has a cylinder block (76) in a housing (12). The cylinder block has a groove defined by a pair of parallel side walls (186,188) to receive a bearing (138) guided by the groove. The blade pushes against a piston-roller (132) and the cylinder block is preloaded circumferentially. The claims include a method of assembly for the compressor

Vane for a rotary expansible chamber e.g a compressor

Vane (60) for a rotary expansible chamber has first tip (61), second tip (63) and body (65) interconnecting the tips. At least one tip is formed of a first alloy containing a lubricant and the body is formed of a second alloy containing inorganic particles, preferably an oxide, which reduce the coefficient of expansion of the second alloy. A preferred lubricant is a porous C preform which is impregnated with the first alloy. Method for making the vane is claimed.

ROTARY PISTON / CAM ENGINE

Sliding vane compressor or motor - has vanes reciprocated in grooves along rotor by shape of walls of chamber

Paddle vacuum pump for automobile servo brake comprises hollow cylindrical body containing eccentrically rotating rotor in which paddle slides between retracted and extracted positions to define separation wall between two body compartments

The vacuum pump comprises a cylindrical hollow body (3) and a cylindrical rotor (7) rotating eccentrically in the body. A paddle (11) slides in a radial groove (13) of the rotor between retracted and extracted positions so that it defines, during its rotation with the rotor, a separation wall of variable length between two body compartments. The paddle has a hole (25) located, in its extracted position, between the outer wall of the rotor and the internal wall of the body. The hole has a non-return valve (27) such that the wall is sealed during a rotation in a first direction (F1) whilst it can be passed through by a fluid during rotation in the opposite direction (F2).
