Abstract
In coolant systems oil mixed with the coolant is often removed in a separate oil separator on the high-pressure side of the compressor. In order to obtain a compact design in a coolant system comprising a unit including an oil-injection rotary compressor, a pressure-gas cooled driven motor and an oil separator, the oil separator is applied directly to the drive motor connected to the rotary compressor.
