A compressor includes a normally open discharge valve assembly for controlling compressed refrigerant flow from the discharge chamber through the compression members. This controlling of flow results in an increased performance for the compressor by reducing recompression volume and the elimination of reverse rotation at shut down. The discharge valve assembly includes a valve seat, a valve plate and a valve stop secured within a recess formed within the compressor. The valve stop and the valve seat include a contoured surface which is engaged by the valve plate when it opens and closes. The contoured surface control the movement of the valve plate.

[ What is claimed is:] [1.]1. A compressor assembly comprising:a shell defining a discharge chamber;a compressor having a discharge area;a discharge valve disposed between said discharge area and said discharge chamber, said discharge valve movable between an open position where fluid flow between said discharge area and said discharge chamber is permitted and a closed position where fluid flow between said discharge chamber and said discharge area is prohibited, said discharge valve comprising:a valve seat disposed within a recess defined by said compressor;a valve plate disposed within said recess adjacent said valve seat, said valve plate including a first annular ring and a movable portion, said movable portion including a first plate portion extending radially inward from said first annular ring and being movable between a first position adjacent said valve seat to place said discharge valve in said closed position and a second position spaced from said valve seat to place said discharge valve in said open position; anda valve stop disposed within said recess adjacent said valve plate, said valve stop defining a contoured surface for controlling said movement of said movable portion of said valve plate.
