Housing construction for reciprocating piston type compressor

摘要

A compressor is described having a pair of casings fastened together by a plurality of bolts. A piston is located for reciprocation within a cylinder bore formed in the casings. A cam plate is mounted on a rotary shaft supported by the casings to reciprocate the piston. The cam plate is held by the casings between a pair of thrust bearings. The casings include adjoining surfaces fitted to each other and a member sandwiched between the adjoining surfaces of the casings for absorbing dimensional tolerances of the casings, cam plate and thrust bearings according to the deformation of the member.
