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 shaft seal seals a rotary shaft surface to prevent fluid from moving between a high-pressure area and a low-pressure area. The shaft seal has a lip type ring fitted on the side of the high-pressure area of the rotary shaft. The lip type ring further includes a lip ring, a plurality of first portions and a plurality of second portions. The lip ring is located around the rotary shaft. The lip ring has a ring surface. The first portions are formed on the ring surface to slidably contact the rotary shaft surface. The first portions guide the fluid towards a space between the ring surface and the rotary shaft surface as the rotary shaft is rotated. The second portions are formed on the ring surface. The second portions prevent the fluid in the space from leaking into the low-pressure area.

摘要： Lubricating oil feeding mechanism has an oil-collecting recess and an oil-supplying groove formed on the wall of the housing. The oil-collecting recess connects a gap defined between the through hole and the bolt to the oil-supplying groove, the gap being in the upper position with respect to a sliding part to be lubricated in the housing in an operating state of the mounted compressor. The oil-collecting recess extends from the gap in the circumferential direction of the drive shaft, and the oil-supplying groove upwardly extends toward the oil-collecting recess. The oil-supplying groove is arranged so as to guide lubricating oil to the sliding part. Lubricating oil adhered on the bolt can be collected to the oil-collecting recess via the gap, and is fed to the sliding part through the oil-supplying groove. Therefore, a large amount of lubricating oil in a swash plate chamber can be utilized to lubricate the sliding part.

摘要： A refrigerant compressor includes a compression mechanism, a discharge passage, and an oil separator. The compression mechanism compresses a refrigerant gas containing a lubricant oil. The refrigerant gas that has been compressed by the compression mechanism flows through the discharge passage. The oil separator is arranged in the discharge passage and separates the lubricant oil from the refrigerant gas flowing in the discharge passage. The oil separator has a rotator that causes the refrigerant gas to flow around the axis of the rotator and a circumferential wall that encompasses the rotator and extends along the axis of the rotator. The rotator and the circumferential wall define a separation zone in between. The lubricant oil is separated from the refrigerant gas by the flow of the refrigerant gas around the rotator in the separation zone. The circumferential wall has an oil outlet that allows the separated lubricant oil to flow to the exterior of the oil separator. The oil separator has an inlet port that allows the refrigerant gas to flow into the separation zone and an outlet port that allows the refrigerant gas to flow out of the separation zone. The rotator is arranged between the inlet port and the outlet port. The inlet port and the outlet port are arranged so that an inlet direction of the refrigerant gas flowing through the inlet port is substantially parallel with an outlet direction of the refrigerant gas flowing through the outlet port.

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.

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.
摘要翻译：可变排量压缩机包括可与驱动轴同步旋转的旋转阀。旋转阀包括一端封闭的中心孔，另一端与抽吸室恒定连通，并且连通孔间歇地提供中心孔与从曲柄室延伸的气体抽出通道之间的流体连通旋转阀的旋转。通过气体提取通道从曲柄室流向吸入室的制冷剂气体的量通过气体提取通道流过的制冷剂气体的量精确地减少，除非由旋转阀关闭。因此，即使气体提取通道的截面面积增加到能够防止污泥和其他异物堵塞的程度，并且确保加工精度和生产率，进入曲柄室的气体量的增加在从大排量运转向低位运转的转变时，能够抑制压缩机的动力损失的增加。
