FIELD: pump and compressor industry.

SUBSTANCE: single-stage liquid-ring machine comprises rotating cylindrical housing 1, an impeller with eccentricity and possibility of rotation placed in it on a fixed distribution shaft with a partition forming an input branch pipe at one end of the shaft and an output branch pipe at the other end. On the inner cylindrical surface of housing 1 there are blades 2 installed. Blades 2 of housing 1 and blades 3 of impeller are equipped with magnetic elements, which face each other with similar poles.

EFFECT: invention is aimed at elimination of mechanical contact of blades 2 of housing 1 with blades 3 of impeller, elimination of friction and wear of surfaces and at the same time ensuring the possibility of transferring rotation from housing 1 to impeller.
