摘要： A variable capacity type compressor has a swash plate, pistons reciprocating in the cylinder bores, a suction chamber, and a discharge chamber. A check valve arranged in the compressor. The check valve has a valve seat member having a flow passage and a valve seat, a case attached to the valve seat member, and a valve element arranged in the case for cooperation with the valve seat. The case has a communication hole formed therethrough to allow the gas to flow from the flow passage through the communication hole to the outside circuit. An annular groove is formed in the outer peripheral surface of the valve element to allow a leaking gas to flow from the clearance space between the valve element and the valve housing to the exterior of the valve housing.

摘要： A variable displacement compressor includes a cylinder block having cylinder bores and a center bore, a drive shaft extending into the center bore through a crank chamber, an adjusting screw threaded into the center bore for axially supporting one end of the drive shaft via a thrust bearing and adjusting an axial gap of the thrust bearing, a plurality of pistons provided in the cylinder bores and moved reciprocally with the rotation of an inclined plate, and a belleville spring interposed between the thrust bearing and the adjusting screw. The adjusted spring force of the belleville spring is always added to an axial force applied to the drive shaft. The repeat of contact/release between the rotor and the thrust bearing, that is caused by the periodic increase/decrease of the compression reactive force, is prevented, and the axial vibration of the drive shaft is prevented.

摘要： A controller normally supplies current the magnitude of which corresponds to a required cooling performance of a refrigeration circuit to a displacement control valve. As a result the compressor displacement is adjusted in accordance with the required cooling performance (usual displacement control). When a vehicle is quickly accelerated, the controller temporarily eliminates the current value to the control valve to minimize the compressor displacement (displacement limiting control). When the control is switched from the displacement limiting control to the usual In displacement control, the controller changes the current value from zero to a target value, which corresponds to the required cooling performance, taking a predetermined restoration time. For an initial period of the restoration period, the current value is set greater than a corresponding value on a direct proportional line, which represents a constant rate of change from zero to the target value. As a result, the control is smoothly and quickly switched from the displacement limiting control to the usual displacement control.

摘要翻译： 控制器通常向位移控制阀提供与制冷回路所需的冷却性能对应的电流。 因此，根据所需的冷却性能（通常的位移控制）来调整压缩机的位移。 当车辆快速加速时，控制器临时消除控制阀的当前值，以最小化压缩机排量（位移限制控制）。 当控制从位移限制控制切换到通常的位移控制时，控制器将预定的恢复时间将当前值从零改变为对应于所需冷却性能的目标值。 对于恢复期的初始期间，将当前值设定为大于直接比例线上的对应值，其表示从零到目标值的恒定变化率。 结果，控制从位移限制控制平稳地快速切换到通常的位移控制。

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.
