Abstract: Liquid refrigerant produced in the condenser of a refrigeration system is directed into an expansion device. The expansion device throttles the high pressure liquid refrigerant into the compressor drive motor housing of the compressor assembly within the refrigeration system.

As the jacket fills with liquid refrigerant, a portion of the refrigerant is directed through passages in the motor stator into contact with the motor rotor. Liquid refrigerant overflowing the jacket and flowing out the ends of the motor through the gap between the rotor and stator drains to the lowermost portion of the motor housing from where it is directed to a second expansion device.
