ABSTRACT:
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.
