Abstract
A hermetically sealed electric motor compressor, comprising a hermetically sealed casing, a reciprocating compressor unit mounted within the casing and compressing a working fluid, the compressor unit having a first discharge passageway, a valve assembly mounted within the casing and opening and closing the first discharge passageway, the valve assembly having a second discharge passageway, a discharge port mounted to the second discharge passageway within the casing and including a muffler. The muffler defines a plurality of resonance chambers. The discharge port includes a base plate having a projection. The valve assembly includes a reed valve assembly including a reed valve and a valve backer mounted behind the reed valve. The valve assembly includes a valve seat defining a recess receiving the reed valve assembly, and an elastic gasket and a holder elastically holding an end of the reed valve assembly within the recess so that the projection of the base plate pushes the end of the reed valve assembly on the bottom of the recess by means of the gasket. The valve backer limits the degree of opening of the reed valve and accelerates the return speed of the reed valve.
