Kompressor

摘要

A double-headed type compressor having a solid cam plate is disclosed. A disk plate (4) is rotatably supported on a drive shaft (3) for driving each piston (5) along a reciprocating path. The disk plate (4) is curved in a single direction to form solid cam surfaces (S1)(S2). The cam surfaces (S1)(S2) transform a single rotation of the disk plate (4) into two reciprocating movements of the piston (5). Cam followers (23)(24) provided between the disk plate (4) and the piston (5) are formed to be comformable to the cam surfaces (S1)(S2). The cam followers (23)(24) roll on the piston (5), and slide on the cam surfaces (S1)(S2).
