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 shaft sealing assembly is located in a suction chamber of a swash plate type compressor to seal the space between a drive shaft and a housing. A first end portion of the drive shaft is supported by a first radial bearing. A second end portion of the drive shaft is supported by a second radial bearing. The suction chamber is closer to the first end portion of the drive shaft than the first radial bearing is. An axial passage is formed in the drive shaft to connect the suction chamber to the crank chamber. An inlet of the axial passage is closer to the second end portion than the second radial bearing is. An outlet of the axial passage is closer to the second end portion than the first radial bearing is.

摘要： A suction chamber and a discharge chamber are defined in a front housing member. A crank chamber is defined between a cylinder block and a rear housing member. A drive shaft passes through the suction chamber and extends from a front end of a housing. The drive shaft is supported by the housing. A shaft sealing assembly for sealing the drive shaft is located in the suction chamber. In the cylinder block and a valve plate, a bleed passage is formed for connecting the crank chamber with the suction chamber. The bleed passage is inclined downward toward the suction chamber. The outlet of the bleed passage is above the shaft sealing assembly. In the suction chamber, a reservoir, which stores lubricating oil supplied through the bleed passage, is surrounds a lower part of the shaft sealing assembly.

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.
