ABSTRACT:
A gas compressor, such as a rotary vane one, for a refrigeration system is equipped with a supplementary inlet. By this gas in the liquid phase is injected into the compression chamber and reduces the temperature of the vaporized coolant gas as it is being compressed. This liquid gas is tapped from the normal refrigeration circuit. It can also be used, prior to injection, to cool oil circulated over the motor by a pump which the motor drives as well as the compressor.
