ABSTRACT:
A valve apparatus of a hermetic type compressor enables an easy mounting of an exhaust valve and a valve spring to an accurate position within a reentrant groove formed in a cylinder head, decreases the number of elements of the valve apparatus to facilitate the assembly and reduces a dead volume to enhance efficiency of the compressor. The valve apparatus includes a cylinder head having a reentrant groove with an exhaust hole, the exhaust valve installed to be opened/closed on the upper surface of the exhaust hole, the valve spring in contact with an upper surface of the exhaust valve, a head cover and a packing interposing between the cylinder head and head cover for preventing a leakage of the refrigerant gas.
