FIELD: mechanical engineering.
SUBSTANCE: invention relates to compressors with a liquid ring. Compressor comprises housing 1 with working chamber installed with possibility of rotation from electric motor, right and left end covers 4 and 3, liquid ring 22 formed in chamber. Compressor is equipped with an auxiliary pump, a set of shutoff valves, suction and injection gas valves 12 and 7 made in cover 4. In cover 4 there are also injection grooves 8 for liquid. In cover 3 there are suction grooves 6 for liquid. Auxiliary pump by means of a set of shutoff valves is made with possibility of pumping liquid into liquid ring 22 from the tank and suction from liquid ring 22 of liquid into the tank to increase or decrease the volume of the working chamber.
EFFECT: invention is aimed at increasing the overall isothermal efficiency by increasing the hydraulic efficiency by excluding the impeller from the main working members.
