CYLINDER HEAD AND VALVE PLATE ASSEMBLY FOR RECIPROCATING COMPRESSOR

Title:

CYLINDER HEAD AND VALVE PLATE ASSEMBLY FOR RECIPROCATING COMPRESSOR

Document Type and Number:

WIPO Patent Application WO2004106734

Kind Code:

A3

Abstract:

A reciprocating compressor (10) that includes a cylinder block (18) with a plurality of cylinder bores (16). A piston (12) is positioned in each bore (16). Each piston (12) is mounted to move in response to the a crankshaft (14), causing each piston (12) to reciprocate within the cylinder bore (16). The compressor (10) further includes a cylinder head (20) which includes bores (22) corresponding to the bores in the cylinder block (18). The cylinder head (20) includes a suction port (28) in fluid communication with a source of compressible gas and a plurality of suction plenum in the cylinder head (20). The cylinder head (20) also includes a discharge plenum in communication with the outlet ports of the valve plate. Interposed between the cylinder head (20) and the cylinder block (18) is a valve plate assembly (50) having a discharge valve (120), and a discharge valve retainer (100) having a pair of radii assembled to the valve plate by snap fitting a cylinder head gasket (60) over the discharge valve and retainer.
