ABSTRACT:
A discharge valve assembly, comprising a reed valve and an overlying valve retainer, is cantilever mounted on the axially outer surfaces of cast iron main and outboard bearings of a rotary vane compressor. Each valve assembly includes a round mounting end having an off-center hole extending through the valve and retainer, and an opposite end associated with opening and closing a discharge port extending through the bearing. The mounting end fits within a counterbore on the outer bearing surface and is retained therein by means of a rivet or the like through the off-center hole. The valve assembly is prevented from rotating about the rivet by the sidewall of the counterbore to maintain proper orientation of the valve and retainer so that they precisely cover the discharge port.
