Abstract

By changing the inclination of a cam plate (19), the stroke of a piston (23) is changed to change the discharge displacement a of compressor. A hinge mechanism (22) is positioned between a rotating support (17) and the cam plate (19). The hinge mechanism includes a guide pin (38), and the guide pin transfers the rotational motion of the rotating support (17) to the cam plate (19) and permits inclination of the cam plate. At least a part of the guide pin (38) is hollow.
