Abstract
A discharge valve (100) of a compressor is disclosed. The discharge valve (100) contains a spring-loaded valve body (120). Valve body (120) is preferably made of nonferrous metal like aluminum or magnesium and is coated by a covering (110) of uniform thickness, the covering (110) being preferably made of plastic material like polyetheretherketone (PEEK) by insertion molding. By that way a wear resistant and light-weight discharge valve is produced.
