ABSTRACT:
A liquid ring pump having at least one vane disposed in the portion of the liquid ring between the outer periphery of the rotor and the inner periphery of the housing for controlling the flow of the adjacent liquid to reduce energy losses due to such factors as the curvature of the liquid flow and re-entry of the liquid into the rotor with velocity which does not match the velocity of the liquid already in the rotor.
