Hinge mechanism for variable displacement compressor

摘要

By changing the inclination of a cam plate, the stroke of a piston is changed to change the discharge displacement a of compressor. A hinge mechanism is positioned between a rotating support and the cam plate. The hinge mechanism includes a guide pin, and the guide pin transfers the rotational motion of the rotating support to the cam plate and permits inclination of the cam plate. At least a part of the guide pin is hollow.
