ABSTRACT:
A rotary vane gas compressor e.g. for use in refrigeration is driven by an electric motor which is cooled by a refrigerant liquid passed through a heat exchanger which is attached to the external surface of the stator of the motor. The refrigerant is then passed back into the compression chamber of the gas compressor via a port intermediate between the inlet and outlet ports.
