    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 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： The flow control valve used in a variable displacement refrigerant compressor, which is incorporated in a refrigerating system, and arranged in a controlling passage fluidly interconnecting between a crank chamber and a discharge chamber or a suction chamber to regulate an opening formed in a predetermined portion of the controlling passage in a control characteristics in which when the discharge pressure of the refrigerant discharged from a discharge chamber of the compressor increases, the suction pressure of the refrigerant entering from the refrigerating system into a suction chamber increases. The flow control valve has a pressure sensing member for sensing of one of the suction and the crank-chamber pressure, and a valve element movable to increase and reduce the opening of the predetermined portion of the controlling passage on the basis of sensing of one of the suction and crank-chamber pressures by the pressure-sensing member.

    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 through the flange. A pin is supported in each support hole. The ends of each pin are received in guide holes. 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.

    摘要翻译： 一种改进的涡旋压缩机，其具有可旋转而不倾斜的可动涡旋件。 压缩机具有形成在壳体中的固定涡旋盘。 动涡旋盘容纳在壳体中并与固定涡旋件配合。 动涡旋盘通过曲柄机构由驱动轴驱动。 法兰形成在可动涡旋件的周边并垂直于驱动轴。 在壳体中形成凹槽。 凹槽比凸缘的厚度略宽。 凸缘可滑动地容纳在槽中。 支撑孔延伸穿过法兰。 每个支撑孔支撑销。 每个销的端部接收在导向孔中。 由于凸缘和凹槽的接合防止可动涡旋件倾斜，所以销保持平行于导向孔并跟随引导孔的壁。 结果，避免了销和引导孔的不均匀磨损。
