<p>An improved discharge valve apparatus for a hermetic compressor which is capable of fixing the retainer based on the elastic force of the elastic protrusions formed in the retainer itself and the shape of the head cover engaged with the retainer, for thus reducing the number of parts and the number of processes. The apparatus includes a head cover, a head engaged with the head cover and having a groove formed in an upper surface of the head, a discharge valve inserted into the groove of the head, a valve spring inserted into the groove of the head for limiting a movement of the discharge valve, and placed on an upper surface of the discharge valve, and a retainer inserted into the groove, and positioned on an upper portion of the valve spring, and having elastic protrusions formed at both sides thereof.</p> |
