Title: Compressor valving

Abstract: Valve means for use in a reciprocating compressor having cylinder means with a piston operable therein. The valve means include an inlet body and a discharge valve assembly, with the inlet body having a base incorporating an inner wall member and an outer wall member extending therefrom in spaced, concentric relationship. The wall members have a plurality of spaced recesses therein and a top is secured to the wall members remote from the base so as to define a passageway having a plurality of openings in both the inner wall member and the outer wall member. The volume of internal flow passages is relatively large and thus there is reduced pressure drop of gas passing through the inlet body. The base and the top are bonded to one another by brazing to form the inlet body. The construction is simple, is readily fabricated by mass production techniques, and is relatively inexpensive.
