摘要： An improved variable displacement compressor is disclosed. A compressor has a cam plate (22) that is mounted on a drive shaft (16) for integral rotation therewith. At least one piston (35) is coupled to the cam plate (22). The cam plate (22) is tiltable between its maximum inclining position and its minimum inclining position with respect to an axis of the drive shaft (16). The piston (35) reciprocates in a cylinder bore by a stroke based on an inclined angle of the cam plate (22) and compresses gas that is supplied to the cylinder bore (11a) from an external gas circuit (52) and discharge the compressed gas to the external gas circuit (52) that is connected to the interior of compressor by way of a gas passage (32). The shutter body (28) is urged by a first spring (85, 91) and a second spring (86) in opposite directions. The urging force of the first spring (85, 92) is greater than that of the second spring (86). A shutter body (28) that is biased to disconnect the gas passage (32) from the external gas circuit (52).

摘要： A variable displacement type compressor is disclosed. The compressor includes a housing, a cylinder bore within the housing, a piston located in the cylinder bore, a drive shaft rotatably supported by the housing, a rotary support mounted on the drive shaft, and a cam plate connected to the piston. The cam plate is supported tiltably on the drive shaft and is slidable in axial directions of the drive shaft. The cam plate inclines between a maximum inclination position and a minimum inclination position when the displacement of the compressor is changed. A first moment is applied to the cam plate by a compression reaction force of the piston when the compressor is operating. A hinge mechanism is located between the rotary support and the cam plate. The cam plate is rotated integrally with the drive shaft, the rotary support, and the hinge mechanism. An urging device is located between the rotary support and the cam plate for urging the cam plate toward the minimum inclination angle position. An applying mechanism applies a second moment to the swash plate in the same direction as the first moment when the compressor is not operating.

摘要： A housing (1, 2, 3) of a compressor has a shutter chamber (13) for accommodating a shutter (21). The shutter (21) moves between a closed position, where the shutter (21) stops flow of gas from an external circuit (35) into a suction chamber (3a), and an open position, where the shutter (21) permits the gas flow in response to the tilting motion of a swash plate (15). A coil spring (24), which has a conical shape, is located in the shutter chamber (13) to bias the shutter (21) in a direction toward the open position from the closed position. The spring (24) is arranged to prevent the spring (24) from sliding against the inner wall of the shutter chamber (13) when the spring (24) is expanded or contracted by movement of the shutter (21).
