ABSTRACT:
A compressor assembly is disclosed including a compressor mechanism mounted within a hermetically sealed housing. A cylinder block contains a reciprocating piston in which the piston includes a suction valve assembly and an annular rim that substantially completely fills the discharge port when the piston is at top dead center position, to reduce re-expansion volume. The cylinder head assembly is attached directly to the cylinder block with no intermediate gasket therebetween, permitting coplanar seating of the discharge valve with a correspondingly larger discharge valve seat perimeter permitting faster valve closure and lower pressure loss through the discharge port.
