ABSTRACT:
A hermetic motor-compressor having a compression mechanism section and a driving motor section resiliently supported in a closed container. The compression mechanism part has a cylinder to the top of which are attached a valve seat cover assembly together with a valve seat member, valves and so forth interposed therebetween. The valve seat cover assembly has a base plate which projects laterally beyond the diameter of the cylinder, so as to present wing areas. A cover member which defines gas passages is attached to one side of the base plate, while suction and delivery-side silencer chambers are attached to the other side of the base plate at the wing areas of the latter. Consequently, the silencer chambers are confined within small areas between the cylinder and the base plate of the valve seat cover assembly, so as to reduce the overall size of the compressor.
