Abstract
A notch is provided in the motor end bearing of a rotary compressor in the region of the discharge port. The notch enhances the flow by smoothing the flow path and guiding the flow so as to impinge upon the discharge valve in a glancing manner and reduces the noise from the valve and valve stop and from the turbulent flow through the discharge port. The notch is located along the axis of the discharge valve and on the side of the valve port on which the valve is pivoted.
