ABSTRACT:
A compressor discharge valve assembly utilizing a cylindrical cavity in which is provided a discharge flow control valve and a valve stop for limiting the opening movement of the valve during operation of the compressor. The discharge valve chamber defines a cylindrical portion into which opens an outlet from the compression chamber. A cylindrical recess is provided in the wall of the discharge valve chamber for receiving a securing portion of the valve stop. The valve stop may further include a spacer for maintaining an arcuate backup portion thereof in inwardly spaced relationship to the valve. The valve is biased to engage the discharge valve chamber wall adjacent the outlet passage. The valve may be defined by a resilient arcuate member secured at one end to the valve stop whereby the valve is cantilevered from the securing means to extend over an arc of approximately 180.degree. to have a distal portion disposed in closing relationship to the outlet passage.
