ABSTRACT:
A double-headed piston type compressor has a disk plate. The disk plate is rotatably supported on a drive shaft for driving each piston along a reciprocating path. The plate is curved in a single direction to form a solid cam on its surface. The cam transforms a single rotation of the plate into two reciprocating movements of the piston. Cam followers provided between the plate and the piston are formed to be conform with the shape of the cam. The cam followers contact and roll on the piston, and slide on the cam.
