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.
