ABSTRACT:
A compressor assembly is disclosed including a compressor mechanism mounted within a hermetically sealed housing. A cylinder block assembly, containing a plurality of reciprocating pistons within compression chambers, is covered by cylinder heads. The compression chambers include a discharge valve which permits compressed refrigerant to empty into a common discharge chamber. A pressure relief mechanism, formed by cylinder heads yieldably attached to the crankcase, is included within the compressor to eliminate damage caused by high pressure conditions such as slugging. Alternatively, pressure relief may be created in the common discharge chamber by a yieldably attached cage bearing or a valved port.
