ABSTRACT:
A liquid ring compressor including a separate gas input opening disposed in the control disc of the compressor near the delivery space of the compressor impeller between the suction and the output openings of the control disc. The improvement of the invention comprises the gas input opening comprising a calibrated gas input opening, and the compressor including means for coupling the opening to the compression space of the liquid ring compressor for continuously feeding a pressure-increasing gas ballast to the delivery space of the compressor through the calibrated opening. The pressure increase of the gas pumped by the impeller ahead of the output openings of the control disc in the direction of rotation of the impeller is thereby reduced.
