摘要： A motor driven compressor assembly includes a motor housing having a fluid inlet and a fluid outlet. A motor is disposed within the motor housing and includes a rotor that is coupled to a rotatable shaft and a stator. Several passages fluidly connect the fluid inlet and the fluid outlet. One passage is located radially outward of the stator and another passage extends through the rotatable shaft. A compressor is in fluid communication with the fluid outlet of the motor housing. Operation of the compressor produces a fluid stream through the motor housing. The fluid stream transfers heat away from the motor to cool the motor.

摘要： A portion of the condensed liquid in a condenser is diverted to a generator where it supplies heat to boil off refrigerant from a refrigerant oil mixture and is thereby subcooled. The subcooled liquid is supplied to the motor for cooling. The boiling off of refrigerant in the generator results in an “oil rich” liquid which is supplied to the bearings, etc. for lubrication. One, or more, jet or ejector pumps are preferably used to supply the oil rich liquid to the lubrication distribution system.

摘要： Refrigerant gas at a few psi higher than suction is supplied via labyrinth or annular groove type seals located between the suction side bearings and suction and between the suction side motor bearing and the motor. The buffer gas flow divides with part going to suction and part to a drain along the oil flowing from the bearings.
