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.

Abstract: A hermetic type compressor includes an exhaust valve installed in a reentrant groove formed in a head for opening or shutting an exhaust hole, a valve spring for elastically supporting the exhaust valve, a retainer for restricting the exhaust valve and valve spring by a constant position, and a valve fixing device for fixing the exhaust valve in a fixing part, wherein the valve spring and valve fixing device are integrally formed between the head and head cover. Thus, the structure of the device is simplified, thereby improving the productivity and saving the manufacturing cost. Also, since the exhaust valve and valve spring are strongly fixed, thereby efficiency of the compressor.

Abstract: An improved exhaustion noise suppressing apparatus for a hermetic compressor directed to minimizing vibration of a refrigerator cycle pipe mechanism caused by a pressure difference of an exhausting gas pressure of the exhausting gas which is discharged from the system to the outside of the compressor by providing a damping member for offsetting a pressure wave form of the refrigerant gas to one side of the interior of the exhaustion noise suppressing unit wherein the compressed refrigerant gas discharged from the cylinder and the exhausting chamber is introduced into the loop pipe through the head cover and the exhaustion noise suppressing unit.
