Abstract
A compressor includes a swash plate rotated with a drive shaft in a swash plate chamber, a link mechanism that changes an inclination angle of the swash plate, an actuator rotated integrally with the drive shaft, and an actuator control mechanism. The actuator includes a partitioning body fitted to the drive shaft in the swash plate chamber, a movable body that is coupled to the swash plate and moved 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. The control mechanism changes the pressure of the control pressure chamber to move the movable body. The swash plate includes a fulcrum point, coupled to the link mechanism, and an action point, coupled to the movable body. The fulcrum point and the action point are located at opposite sides of the drive shaft.
