Compressor valving

In a reciprocating compressor having cylinder means and a piston operable therein and valve means for controlling the passage of suction gas to the cylinder means and the discharge of discharge gas from the cylinder means, characterized by the valve means comprising a main valve body, said main valve body comprising a base having an inner annular wall member and an outer annular wall member extending therefrom, the outer wall member being spaced radially outwardly from the inner wall member and the wall members being in spaced concentric relationship, said wall members having a plurality of spaced recesses therein and a top secured to the ends of 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, said top being planar and including a truncated conical portion extending therefrom, the base and the top being bonded to one another to form the main valve body, said passageway having a relatively large volume and the openings in the inner wall member and the outer wall member being relatively large to provide reduced pressure drop of the gas flow through the main valve body, said suction gas entering said passageway through the openings in the outer wall member.
