摘要： A compressor has a high-pressure relief valve and a low-pressure relief valve. The high-pressure relief valve in use for a discharge region opens when the pressure of gas in the discharge region is more than a first predetermined pressure. The high-pressure relief valve is provided with a first shim. The low-pressure relief valve in use for a suction region opens when the pressure of gas in the suction region is more than a second predetermined pressure which is lower than the first predetermined pressure. The low-pressure relief valve is provided with a second shim. The high-pressure relief valve and the low-pressure relief valve have similar structure to each other.

摘要： The number of seal members relating to a gas flow control valve can be reduced. A displacement control valve 25 is attached to a fixed coupling surface 193 on the outer wall surface of a rear housing 19. A gasket 45 is interposed between end surfaces 362 and 414 of the displacement control valve 25 side and a coupling surface 193. A sealing elastic layer 452 of the gasket 45 is in close contact with the end surfaces 362 and 414, and a sealing elastic layer 453 is in close contact with the coupling surface 193. A pressure supply passage 30 and a gas passage 413 are communicated with each other via a communication port 454 on the gasket 45. A pressure supply passage 31 is communicated with an insertion recess 33 that is communicated with a valve port 431.

摘要： The object of the present invention is to offer an electric type swash plate compressor which is compact and reduced in weight and lightened, and which can efficiently cool down a motor chamber and a crank chamber. The compressor has an electric motor and a swash plate, which are respectively accommodated in the motor chamber and the crank chamber. In the compressor a communication route, which communicates a part except the discharge chamber communicating with an external refrigerant circuit in an inner refrigerant circuit within an outer casing with the motor chamber, is formed. The communication route is formed so as to pass through the crank chamber, and the refrigerant in lower temperature and lower pressure than discharge refrigerant is supplied into the motor chamber and the crank chamber. Accordingly, the improvement of cooling efficiency and the reduction of pressure resisting strength of the casing can be performed.

摘要： A gasket 36 is interposed between an end face 341 of a front housing 11 and an end face 351 of a rear housing 12. A coned disc spring 37 is interposed between an end face 192 of a cylinder 19 and the end face 341 of the front housing 11. When the end faces 341, 351 are caused to approach each other so as to be joined together, the coned disc spring 37 is first held by the end face 341 of the front housing 11 and the end face 192 of the cylinder 19. When the end faces 341, 351 are caused to approach each other further so as to be joined together, the gasket 36 is held between the end faces 341, 351. Thus, it is ensured that the cylinder and the seal material interposed between the first housing and the second housing are held therebetween.

摘要： An improved scroll compressor having a movable scroll that orbits without being inclined. The compressor has a fixed scroll formed in the housing. The movable scroll is accommodated in the housing and mates with the fixed scroll. The movable scroll is driven by a drive shaft via a crank mechanism. A flange is formed at the periphery of the movable scroll and lies perpendicular to the drive shaft. A groove is formed in the housing. The groove is slightly wider than the thickness of the flange. The flange is slidably accommodated in the groove. Support holes extend in the housing. A pin is supported in each support hole. The ends of each pin are received in guide holes through the flange. Since engagement of the flange and the groove prevents the movable scroll from being inclined, the pin is maintained parallel to the guide holes and follows the wall of the guide holes. As a result, uneven wear of the pins and the guide holes is avoided.

摘要： An air-conditioning system capable of always effectively performing the heating function by selectively using one of a cooling circuit and a heating circuit sharing a variable displacement type compressor is disclosed. An electromagnetic capacity control valve (43) controls the discharge capacity of a variable displacement type compressor (25) in response to the differential pressure between the discharge pressure Pd of a discharge chamber (132) and the suction pressure Ps of a suction chamber (131). The energization and deenergization of the capacity control valve (43) is controlled by a control unit (59). When a cooling command switch (63) is turned on, the control unit (59) deenergizes a switching valve (29) thereby to control the cooling operation while at the same time controlling the discharge capacity by the capacity control valve (43). When a heating command switch (64) is turned on, on the other hand, the control unit (59) energizes the switching valve (29) thereby to control the heating operation while at the same time controlling the discharge capacity by the capacity control valve (43).

摘要： A piston-operated compressor, of swash plate type and using CO2 as a refrigerant, having a casing member in which a cylinder bore is formed to have a cylindrical peripheral wall surface and a piston reciprocating for compression in the cylinder bore and being formed of an aluminum alloy. The outer peripheral surface of the piston is coated with a film of a fluororesin material, and a piston ring of an iron metal is fitted in the neighborhood of the top portion of the piston to permit the CO2 refrigerant to be compressed under high pressure. A first oil groove is formed in peripheral direction in parallel to and below the vicinity of the groove at the top portion of the piston in which the piston ring is fitted, and a second oil groove is formed below the first oil groove extending along the axial direction in parallel with the central axis of the piston.

摘要： An improved air conditioning system that cools or heats air very rapidly after being started. The system includes a main heater and a cooler which also functions as an auxially heater. The cooler includes a variable displacement compressor for compressing refrigerant gas. The compressor has a crank chamber and a discharge chamber. A crank mechanism is accommodated in the crank chamber. Compressed refrigerant gas is supplied to an external refrigerant circuit via the discharge chamber. The discharge chamber is connected to the external refrigerant circuit by a passage. A throttle valve is located in the passage. The throttle valve closes the passage immediately after the compressor is started, which quickly increases the pressure of the discharge chamber. As a result, the displacement of the compressor is increased quickly, and rapid heating or cooling results.
