ABSTRACT:
Disclosed is a compressor having a plate rotatable about an axis of a rotary shaft and a piston connected to the plate, wherein the plate causes the piston to reciprocate between a top dead center and a bottom dead center of its stroke in accordance with the rotation movement of the plate. A cam surface is provided with the plate for actuating the piston. A shoe engages with the plate for transmitting the rotation movement of the plate to the piston. A recess is formed on the piston for restricting rolling of the shoe on the plate for causing the shoe to slide on the plate to reduce the pressure caused by the contact between the cam surface and the shoe.
