ABSTRACT:
A hermetic reciprocating piston refrigeration compressor utilizes separate cylinder head members for the discharge and suction plenum chambers adjacent the discharge and suction valves. The two cylinders heads extend over substantially the entire area of the valve plate at the end of the cylinder carrying the valves. A discharge cylinder head is formed of metal while the suction cylinder head is formed of a plastic material of low thermal conductivity to minimize heat transfer between the discharge and suction plenums. The suction cylinder head is formed as a unitary member to include also passages and a portion of the suction muffler and is secured in place by a single fastening member.
