ABSTRACT:
A compressor assembly is disclosed including a compressor mechanism mounted within a hermetically sealed housing. A cylinder block contains a reciprocating piston having a suction valve assembly. The piston includes a head with a deep semitorus shaped annular groove with a similarly shaped solid suction valve that seats thereto. A retaining mechanism including a clamping bolt with a plurality of radially extending fingers is used to reduce valve inertia and impact forces. The fingers behave as cantilevered beam springs.
