Abstract
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.
