Abstract
A compressor valve assembly is disclosed. The valve assembly includes a guide having a cylindrical cup portion and a cylindrical stem portion that extends axially in a socket where the guide can be removably affixed to a stop plate. The disclosed valve assembly is conducive to user-friendly serviceability while realizing an increased flow area with operational capability at relatively higher pressures and practically no susceptibility to bending stresses.
