Valve keeper for a valve of a reciprocating compressor

摘要

A cylinder assembly of a reciprocating compressor has exhaust valve elements including an exhaust valve reed, a stopper and a keeper. The keeper has two opposite fixed ends pressed against a valve seat by the cylinder head. Each of the fixed ends of the keeper includes an elastically deformable portion arranged to be elastically deformed by a pressing force of the cylinder head. This ensures accurate positioning of the keeper, regardless of the magnitude of the pressing force from the cylinder head.
