摘要： A variable displacement swash compressor includes a housing, a drive shaft, a swash plate, a link mechanism, a piston, a conversion mechanism, an actuator, and a control mechanism. The swash plate is rotatable together with the drive shaft in a swash plate chamber. The conversion mechanism reciprocates the piston in a cylinder bore. The actuator changes the inclination angle of the swash plate. The actuator is rotatable integrally with the drive shaft. The actuator includes a partitioning body, a movable body, and a control pressure chamber. The control mechanism changes the pressure of the control pressure chamber to move the movable body. The movable body is adapted to pull the swash plate and increase the inclination angle when the pressure of the control pressure chamber increases.

摘要： A capacity control valve device for a variable capacity swash plate compressor which includes at least one piston, a suction port, a suction chamber, and a refrigerant inlet passage communicating the suction port with the suction chamber, in which each piston has its stroke changed to control delivery quantity of the compressor. The control valve device is arranged at an intermediate portion of the refrigerant inlet passage, for controlling differential pressure between the suction port and the suction chamber. The control valve device includes a valve element, a first urging member for urging the valve element in a valve-opening direction, an accumulator for accumulating high-pressure refrigerant gas having higher pressure than pressure within the suction chamber to build up pressure therein for urging the valve element in a valve-closing direction, a high-pressure passage for introducing the high-pressure refrigerant gas into the accumulator, and a pilot valve arranged at an intermediate portion of the high-pressure passage for controlling a flow rate of the high-pressure refrigerant gas into the accumulator in dependence on the pressure in the suction port. The pilot valve has a valve element, and a second urging member for urging the valve element in a valve-closing direction. The control valve device comprises a pressure control passage opened by the pilot valve for permitting the high-pressure refrigerant gas accumulated within the accumulator to escape, when the pilot valve operates in the valve-closing direction.
