ABSTRACT:
A relieved portion is provided in the motor end bearing of a rotary compressor in the region of the discharge port. The relief is in the nature of a chamfer or the like and enhances the flow by smoothing the flow path. The relief is limited to the portion of the motor end bearing overlying the cylinder bore so as to limit its contribution to the clearance volume.
