ABSTRACT:
A liquid ring machine having a housing in which there is rotatably arranged a rotor having its axis displaced by an amount of eccentricity with respect to the axis of the housing. The liquid ring machine is capable of optimal use in simple manner for both vacuum and compression operations. This result is obtained by ensuring that amount of eccentricity from the housing axis to the rotor axis is directed to oppose the direction of the force of gravity in vacuum operations and is directed in the direction of the force of gravity in compression operations.
