ABSTRACT:
A variable displacement compressor includes a swash plate supported tiltably on a drive shaft and slidable in axial directions of the drive shaft. The swash plate has a central support hole into which the drive shaft is inserted. The swash plate has a top dead center point for positioning the piston at a top dead center position and a bottom dead center point for positioning the piston at a bottom dead center position. The center of gravity of the swash plate is displaced from the axis of the drive shaft toward the top dead center point. This location of the center of gravity maintains the radial position of the swash plate relative to the drive shaft by centrifugal force acting on the swash plate when the swash plate rotates. As a result, the compressor is quieter and more stable.
