Abstract
A discharge system for a hermetic compressor of the type that comprises a shell in whose interior a cylinder is housed defining a compression chamber in conjunction with a rolling eccentric piston driven by an electric motor, such cylinder having a discharge orifice in communication with a discharge valve to communicate the compression chamber with a discharge muffler chamber. The discharge orifice has a surrounding wall defining a valve seat on the internal face of the discharge muffler chamber. The discharge valve in the muffler chamber comprises a disc; disc guide means fastened in an inner wall of the discharge muffler chamber; and an elastic biasing element forcing the sealing disc against the valve seat and dimensioned to allow the sealing disc to be displaced off the when a certain pressure in the compression chamber is reached.
