ABSTRACT:
A discharge valve assembly is disclosed which includes an improved valve guide and spring retainer having a continuous annular surface surrounding the discharge valve and operative to guide movement thereof. An improved discharge valve is also disclosed which includes an arcuate lower peripheral surface portion defined by a surface of revolution of a curve which surface may form the surface of a zone of a sphere. The annular guide surface and improved discharge valve cooperate to the noise level emanating from the compressor valve assembly and to facilitate manufacture and assembly of the components thereof.
