ABSTRACT:
A rotary compressor in a cooling or a heat pump system which is provided with an oil injector and includes an oil separator on the high pressure side of the system. Oil is returned to the compressor for lubrication, cooling and sealing and is normally caused to circulate by means of the natural pressure differences in the cooling system. When the pressure level is too small to provide sufficient oil circulation, an oil pump is connected. By employing a pressure controlled regulating valve in the system, which serves both as a pressure regulating and a flow regulating valve, the oil pump may be caused to run idle when a sufficient pressure difference has been attained in the system.
