ABSTRACT:
Disclosed is a compressor having a plate rotatable about an axis of a rotary shaft and a piston connected to the plate. 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. Cam surfaces are provided on the plate for actuating the piston. The cam surfaces have first portions for driving the piston toward the top dead center, and second portions for driving the piston toward the bottom dead center. Transmission members are interposed between the piston and the cam surface for transmitting the rotational movement of the plate to the piston. The first and second portions cause the transmission members to follow on the cam surfaces. At lease one of the first and second portions are arranged to have a normal line extending obliquely to the axis of the rotary shaft for constant contact between the transmission members and the one of the portions.
