Orbiting vane compressor with side-inlet structure

Disclosed herein is an orbiting vane compressor with a side-inlet structure that is capable of compressing air in a cylinder according to an orbiting movement of an orbiting vane, the orbiting vane compressor being applied to a refrigerant compressor having refrigerant gas inlet and outlet channels isolated from each other, thereby increasing the sectional area of the refrigerant gas inlet channel. Refrigerant gas is introduced into the cylinder from the side of the cylinder, is compressed in the cylinder, and is then discharged upward or downward out of the cylinder. As a result, refrigerant gas introduced into the cylinder through the refrigerant gas inlet channel is prevented from being heated by compressed refrigerant gas discharged through the refrigerant gas outlet channel.

Nutating fluid-mechanical energy converter

One example of a nutating fluid-mechanical energy converter includes a stator and a rotor. The stator includes an outer cylinder having a longitudinal passage (101) and an inner guide cylinder disposed longitudinally within the outer cylinder. The inner guide cylinder and outer cylinder are concentric and define an annulus for fluid flow. A longitudinal guide is attached to an outer surface of the inner guide cylinder and extending outwardly toward an inner surface of the outer cylinder. The rotor is positioned in the annulus to be eccentric relative to the outer cylinder. The rotor has a sidewall with a guide opening to receive the longitudinal guide. Fluid flowing through the annulus imparts a torque on the rotor causing the rotor to nutate within the annulus. The nutational motion of the rotor can be converted into a rotational motion using a suitable rotary output device.

Nutating fluid-mechanical energy converter

One example of a nutating fluid-mechanical energy converter includes a stator and a rotor. The stator includes an outer cylinder having a longitudinal passage (101) and an inner guide cylinder disposed longitudinally within the outer cylinder. The inner guide cylinder and outer cylinder are concentric and define an annulus for fluid flow. A longitudinal guide is attached to an outer surface of the inner guide cylinder and extending outwardly toward an inner surface of the outer cylinder. The rotor is positioned in the annulus to be eccentric relative to the outer cylinder. The rotor has a sidewall with a guide opening to receive the longitudinal guide. Fluid flowing through the annulus imparts a torque on the rotor causing the rotor to nutate within the annulus. The nutational motion of the rotor can be converted into a rotational motion using a suitable rotary output device.

SCROLL COMPRESSOR

The present invention relates to a scroll compressor. The scroll compressor includes: a casing; a rotating scroll and a non rotating scroll which suck a refrigerant from a suction space of the casing and discharging the refrigerant to a discharge space of the casing by compressing the refrigerant in a compression chamber; and a capacity varying unit having a first valve device and a second valve device, which are engaged with each other, in the casing and selectively bypassing a part of the refrigerant in the compression chamber. Thereby, the scroll compressor prevents the refrigerant from leaking to the outside of the compressor and reduces a pressure loss as a bypass flow path became shorter. The size and the costs of the compressor, and manufacturing costs are reduced, and the capacity of the compressor can be varied with less operation force and less power. COPYRIGHT KIPO 2016 ...

ROTARY COMPRESSOR

A rotary air compressor includes a rotor which rotates within a housing and controls communication through inlet and outlet ports provided on the housing and compresses air communicated through the inlet port for delivery to the outlet port. The inlet and outlet ports are provided with check valves controlling communication therethrough.

Slider adapting apparatus for orbiting vane compressors

Disclosed herein is a slider adapting apparatus for orbiting vane compressors. A circular vane of an orbiting vane is disposed in an annular space defined in a cylinder. A pair of sliders is coupled with the circular vane for performing reciprocating movement along the annular space while being in tight contact with both ends of an opening formed at the circular vane to seal between compression chambers formed in the annular space. The slider adapting apparatus comprises a gap defined between the sliders, which are spaced apart from each other, and a gap maintaining part for maintaining the gap while increasing and decreasing the gap. Using the slider adapting apparatus, damage to parts and a locking phenomenon due to severe interference between the circular vane and the sliders are prevented, and therefore, a drive unit of the orbiting vane compressor is effectively prevented from suffering overload and catching fire.

ROTARY COMPRESSOR

In a rotary compressor of a vane rotary type, an outer peripheral surface of an eccentric portion of a shaft on a side adjacent to a center of the shaft is located radially inwardly of an outer peripheral surface of a main shaft inserted in a main bearing and that of an auxiliary shaft inserted in an auxiliary bearing.

In addition, since the bypass holes are disposed in close proximity to each other, the operation capacity of the compressor can be easily changed with only one bypass valve, thereby increasing the reliability while reducing the number of bypass valves. 스크롤, 바이패스홀, 중간압챔버, 바이패스밸브 Scroll, bypass hole, intermediate pressure chamber, bypass valve

A compressor according to the present disclosure may include a cylinder including an outer cylinder portion and an inner cylinder portion, and a vane portion connected between the outer cylinder portion and inner cylinder portion, which is fixed to a casing. Furthermore, a rolling piston may be slidably coupled to the vane portion to form an outer compression space and an inner compression space while making a turning movement between the outer cylinder portion and inner cylinder portion. Through this, the weight of a rotating body can be reduced to obtain a low power loss with respect to the same cooling power and a small bearing area, thereby reducing the refrigerant leakage as well as easily changing the capacity of a cylinder in an expanded manner. Moreover, refrigerant may be discharged in opposite directions to each other in each compression space, thereby reducing the vibration noise of the compressor. In addition, a back pressure groove may be formed on an upper surface of the drive transmission portion of the rolling piston, thereby reducing a friction area between the rolling piston and the upper bearing as well as reducing a friction loss between the rolling piston and the upper bearing due to oil filled into the back pressure groove.
