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.

摘要： A hermetically sealed type compressor having a valve seat plate equipped with a plurality of suction holes to effectively suck a refrigerant into a cylinder and capable of preventing the breakage of the valve seat plate coming from the opening and closing operations of a suction reed valve. A partition 50 between adjacent suction holes in the valve seat plate 15 is made to have a constant dimension, thus maintaining a given strength of the partition section and preventing the breakage of the partition 50 coming from the opening and closing movements of the suction reed valve. In addition, in the valve seat plate 15, a cavity 22 or a groove 37 is formed to define a low-pressure space 36 communicating with the plurality of suction holes 24, 25, thereby reducing the suction resistance.

摘要： A hermetically sealed motor compressor for use in a small-size refrigerating machine, refrigerator, freezer and the like has a compressor on which is mounted a silencer comprising in combination a suction muffler of thermal insulating and a discharge muffler made of formed metal plates. The suction muffler has an suction port disposed near the open end of a suction coupling fixed to a sealed casing, and also has an connection pipe connected to a compressor cylinder and having a distal end fitted directly in a hole defined in an head plate which is mounted on the head of the cylinder. A refrigerant gas as it is introduced from the suction coupling into the sealed casing can be drawn into the cylinder through the suction port, the suction muffler and the connection pipe to minimize heat transfer to the suction gas, so that the compressor can increase its volumetric efficiency.
