    Abstract: A motor pump (10) includes a pump head (22) for pressurizing a fluid and an electric motor for driving the pump head. Within the pump head, radial forces produced in two symmetrical pumping zones are balanced against each other to reduce stress and increase efficiency. High pressure fluid exits the pump and follow a flowpath through the motor air gap, through an end bearing carrying a distal end of a hollow pump rotor shaft, and returning to the pump head by way of the hollow rotor shaft (44) . The motor rotor shaft (44) is axially movable with respect to the pump head, which effectively floats the motor rotor in high pressure fluid. A motor stator barrier (56) can inhibits fluid flow into the motor stator (90) , and a rotor barrier (112) can inhibits fluid flow into the motor rotor. The rotor barrier can is efficiently attached to the rotor shaft in such a way as to stiffen the shaft and increase its bending resistance. The walls of the stator barrier can are thin and expand under fluid pressure to make contact with and find structural support from the stator laminations and motor endshield. Overheat conditions within the motor, as well as the pump head, are detected by positioning a heat sensing switch (130) within the motor adjacent the pump head (22) to shut down the motor (14) when an overheat condition is detected.

    Abstract: Process for regulating a compressor with motor for a refrigerating system, where the temperature of the cooling site is regulated through an on-off motor mode if the temperature in the compressor exceeds an upper temperature threshold. In addition, the temperature of the cooling site is regulated through a continuous on mode of the motor as soon as the motor has cooled to a lower temperature threshold. The controller converts a variable corresponding to the cooling requirement of the cooling site into a switch signal for a valve, which results in clocked opening and closing of the valve, or uses a frequency converter, which controls the cooling liquid flow through the compressor by regulating the voltage and the frequency of the motor in that the frequency converter converts a variable corresponding to the cooling requirement of a cooling site into a voltage and a frequency for the motor.
