ABSTRACT:
A refrigeration motor compressor assembly has a housing including a lubricant sump in the bottom thereof into which the lower end of the drive shaft and associated rotor extend. A shield is provided which is positioned by the drive shaft and extends above the oil level in the sump in surrounding spaced relationship to the lower end of the rotor. As the rotor rotates within the shield, lubricant contained therein is thrown out of the surrounding shield and a close fit between the shield and the shaft restricts return flow of lubricant into the area occupied by the rotating rotor.
