Abstract (en)

A hermetically sealed rotary compressor is disclosed wherein gas compressed within a compression chamber (85) defined by a cylinder block (84) is discharged through respective discharge ports (130, 140) in the main and outboard bearings (64, 74) defining the ends of the cylinder. Mufflers (90, 92) are provided on the outside ends of the bearings into which the compressed gas is expanded. A constricting gas passageway (160) extending through the bearings (64, 74) and the cylinder block (84) provides a path for constricted flow of gas from one muffler (90) to the other (92). The constricted gas expands upon entry into the other muffler (92), thereby providing a cooler recombined discharge gas for use in cooling oil in the oil sump (114) and cooling the motor stator windings (26).
