Abstract
An improved discharge valve assembly is disclosed for use in refrigeration compressors which includes a combination valve guide and spring retainer extending into a conical discharge gas passage and which includes an annular conical surface positioned in spaced parallel relationship with the sidewalls defining the discharge gas passage. The conical annular surface cooperates with the sidewalls defining the discharge gas passage to provide a diffusing discharge gas flowpath offering improved compression efficiency and sound reduction.
