ABSTRACT:
A hermetically sealed rotary compressor is disclosed wherein gas compressed within a compression chamber defined by a cylinder block is discharged through respective discharge ports in the main and outboard bearings defining the ends of the cylinder. Mufflers are provided on the outside ends of the bearings into which the compressed gas is expanded. A constricting gas passageway extending through the bearings and the cylinder block provides a path for constricted flow of gas from one muffler to the other. The constricted gas expands upon entry into the other muffler, thereby providing a cooler recombined discharge gas for use in cooling oil in the oil sump and cooling the motor stator windings.
