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.

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 is operative to change 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 and the link mechanism are located at opposite sides of the swash plate.

摘要： A variable displacement swash plate type compressor includes a rotary shaft, a swash plate, and an actuator, which changes the inclination angle of the swash plate. The actuator includes a partition body and a movable body, which moves in a direction along the rotational axis of the rotary shaft. The movable body includes a guide surface, which changes the inclination angle of the swash plate, and a sliding portion, which slides on the rotary shaft or on the partition body. When viewed from a direction that is perpendicular to the direction in which the rotational axis of the rotary shaft extends and perpendicular to a first direction, the guide surface is configured such that a perpendicular line or a normal line to the guide surface intersects with the rotational axis of the rotary shaft in a zone surrounded by the sliding portion.

摘要： An actuator of a compressor includes a partitioning body, which is rotatable integrally with a drive shaft and loosely fitted to the drive shaft in the swash plate chamber, a movable body, which is coupled to a swash plate and movable relative to the partitioning body along the axis of the drive shaft, and a control pressure chamber, the pressure of which moves the movable body. A control mechanism changes the pressure of the control pressure chamber to move the movable body. A link mechanism shifts a top dead center of a first head of a piston over a longer distance than a top dead center of a second head of the piston when the inclination angle of the swash plate changes. The actuator is located at the same side as the first cylinder bore, which accommodates the first head, as viewed from the swash plate.
