Abstract

A variable displacement compressor used in air conditioners is provided with a tilting swash plate to vary its displacement. A drive shaft extends through a boss of the swash plate. A hole is defined in the boss by a pair of intersecting conical walls. The position of the swash plate is restricted by the contact between the walls of the hole and the drive shaft. The walls of the hole also allow the swash plate to incline without interference. A bearing element is arranged at a central angled section defined in the walls of the hole. The bearing element is located at a position that is opposite from a hinge mechanism with respect to the drive shaft. A concave seat is provided in the boss at this position to receive the bearing element. The bearing element includes a cylindrical surface engaging the outer surface of the drive shaft.
