ABSTRACT:
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 go 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.
