摘要： In a single-ended swash plate compressor, unbalanced thrust loads in either axial direction are reduced so that thrust loads acting on pistons in the direction of the front end are practically balanced by those in the direction of the rear end, for example, by connecting an intake chamber to a swash plate chamber by means of an adjustment valve to adjust the pressure in the swash plate chamber acting on the front end surfaces of the pistons to a suitable intermediate pressure by the action of the adjustment valve. In a single-ended swash plate compressor with pistons housed in both ends of a cylinder assembly comprising one set of pistons for guidance and another set for compression, discharge pressure is introduced into some of the cylinder bores housing guide pistons and intake pressure is introduced into the cylinder bores housing guide pistons into which discharge pressure is not introduced.

摘要： A variable displacement compressor includes a rotary valve which can rotate synchronously with a drive shaft. The rotary valve includes a center hole with one end closed and with the other end in constant communication with a suction chamber, and a communicating hole intermittently provide a fluid communication between the center hole and a gas extracting passage extending from a crank chamber along with the rotation of the rotary valve. The amount of refrigerant gas flowing back from the crank chamber to the suction chamber through the gas extracting passage is reduced by exactly the amount of the refrigerant gas which can flow through the gas extracting passage unless it is closed by the rotary valve. Therefore, even if the sectional area of the gas extracting passage is increased to an extent of being able to prevent sludge and other foreign matter from clogging it and ensure the processing accuracy and productivity, the increase of the amount of gas fed to the crank chamber at the time of transition from a large displacement operation to a low displacement operation, and the increase in the power loss of the compressor, can be suppressed.

摘要： A compressor including a compressing mechanism accommodated in a housing. The mechanism draws refrigerant from an intake chamber into a compression chamber and discharges the refrigerant from the compression chamber to the discharge chamber. A seal device prevents leakage of refrigerant from the internal space to the atmosphere between the drive shaft and the housing. An isolation chamber, which is separately formed in the housing, accommodates the seal device. A pressure reducing passage reduces the pressure of the isolation chamber to reduce the pressure difference applied to the seal device.
