ABSTRACT:
A motor housing for an air-filled motor incorporates a closed loop system in a cylindrical shell member of the housing which includes a plurality of coolant lift passages and coolant return passages which extend longitudinally along a sidewall of the housing. The lift and return passages communicate with an annular circulation passage at the uppermost portion of the motor housing and at their opposite ends, the passages communicate with a coolant reservoir at high and low pressure regions thereof. An impeller attached to the motor driveshaft is disposed within the fluid reservoir and provides the circulating force necessary to circulate the coolant through the closed loop system.
