摘要： A variable displacement compressor compresses gas supplied from an evaporator of an external refrigerant circuit and discharges the compressed gas to the refrigerant circuit. A check valve is located between the compressor suction chamber and the evaporator. The check valve prevents gas flow from the suction chamber to the evaporator. When the compressor is stopped, a displacement control valve increases the pressure in a crank chamber of the compressor to move a swash plate to a minimum inclination position. The pressure in the suction chamber is increased by gas supplied from the crank chamber. Closing the check valve accelerates a pressure increase in the suction chamber. When the pressure in the suction chamber is increased, the control valve limits a further pressure increase in the crank chamber. As a result, the force that decreases the inclination of the swash plate is limited.
摘要翻译：可变排量压缩机压缩从外部制冷剂回路的蒸发器供给的气体，并将压缩气体排出到制冷剂回路。止回阀位于压缩机吸入室和蒸发器之间。止回阀防止气体从吸入室流到蒸发器。当压缩机停止时，位移控制阀增加压缩机的曲柄室中的压力，以将斜盘移动到最小倾斜位置。吸入室中的压力由曲柄室供给的气体增加。关闭止回阀加速吸入室的压力增加。当吸入室中的压力增加时，控制阀限制曲柄室中的进一步的压力增加。结果，减小斜盘倾斜度的力受到限制。

摘要： A variable type compressor has a housing that houses a crank chamber and rotatably supports a drive shaft. Part of the housing is constituted by a cylinder block. Cylinder bores extend through the housing about the drive shaft. A piston is accommodated in each cylinder bore. A discharge chamber is defined in the housing and connected to the crank chamber by a pressurizing passage. An inclinable cam plate is supported on the drive shaft. The reciprocation of each piston draws refrigerant gas into the associated cylinder bore from a suction chamber and discharges the refrigerant gas into the discharge chamber through a discharge port. The displacement and the discharge of refrigerant gas is controlled by altering the inclination of the cam plate. A collection compartment is provided to receive the refrigerant gas discharged from the cylinder bores. Oil is separated from the refrigerant gas in the collection compartment. The inlet of the pressurizing passage is connected with the collection compartment to supply the separated oil to the crank chamber.

摘要： A displacement control valve for a variable displacement compressor includes a first valve hole forming a part of a supply passage and a second valve hole forming a part of a discharge passage. Displacement of a reciprocating body is transmitted to each of first and second valve bodies so that each valve body opens or closes the corresponding valve hole. When the reciprocating body is within a predetermined displacement range, a double closing state occurs, in which the first valve body closes the first valve hole and the second valve hole closes the second valve hole. When the reciprocating body is out of the displacement range, a single closing state occurs. Therefore, the control valve prevents the first valve hole from opening concurrently with the second valve hole.

摘要： In a variable displacement compressor that draws, compresses, and discharges refrigerant gas, the displacement is adjusted by varying the inclination of a cam plate in accordance with the difference between the pressure in a crank chamber and the pressure in cylinder bores. A pressurizing passage connects the crank chamber to a discharge passage. A bleed passage connects the crank chamber to a suction chamber. A displacement control valve is externally controlled and varies the pressure in the crank chamber by adjusting the opening size of either the pressurizing passage or the bleed passage. A suction control valve closes a duct between the suction chamber and an evaporator when the pressure in the crank chamber exceeds a predetermined level to prevent an excessively high pressure in the crank chamber.

摘要： A first swash plate 18 is coupled to a drive shaft 16 to be rotatable integrally with the drive shaft 16. Single head pistons 23 are coupled to the first swash plate 18 via shoes 25A, 25B. Rotation of the drive shaft 16 rotates the first swash plate 18, which causes the pistons 23 to reciprocate and compress refrigerant gas. The first swash plate 18 supports an annular second swash plate 51 to be rotatable relative to the first swash plate 18 via a ball bearing 52. The second swash plate 51 is arranged between the first swash plate 18and the shoes 25B that receive a compressive load to be slidable with respect to the first swash plate 18 and the shoes 25B. Therefore, the first swash plate reliably slides with respect to the second swash plate.

摘要： A compressor including a housing, a rotary shaft extending through the housing, and a sealing device arranged about the rotary shaft to seal the housing. A shaft bore extends through the housing for insertion of the rotary shaft. An elastomer lip ring seals the housing in cooperation with the rotary shaft, while contacting the peripheral surface of the rotary shaft in a slidable manner. A pressure resistant reinforcement arranged in the shaft includes a backup ring, which is arranged between the elastomer lip ring and the rotary shaft, and a stopper, which is fixed in the shaft bore. The backup ring contacts the elastomer lip ring. The stopper restricts movement of the backup ring in the axial direction relative to the rotary shaft and enables movement of the backup ring in a radial direction relative to the rotary shaft.
