ABSTRACT:
A vane-type rotary pump and a vane-type rotary compressor are integrated into a single unit and are driven by a common shaft. The compressor assembly is positioned at the rear of the pump assembly to minimize the number of mechanical seals required to seal the pump assembly along the shaft. The combined pump and compressor unit is provided with a regulating mechanism for reducing the compressor output during moderate or off modes of the refrigerant circuit.
