Abstract
When liquids are conveyed together in the liquid ring of a liquid ring machine, an increased power requirement and a deterioration of the running characteristics of the rotor result. A liquid ring machine for selectively conveying several liquids has a housing which eccentrically surrounds a rotor and whose end face is closed by lateral shields for the rotor shaft. At least one controlling body is provided with a suction slot and a delivery slot associated with the rotor, and in addition to the delivery slot, has a relief passage located in the delivery area. In order to obtain a liquid ring having an approximately constant thickness, the relief passage is directly connected to the working liquid supply line of the liquid ring machine so that excess liquid flowing out through the relief passage is added directly to the working liquid. The relief passage may also be connected with a closed feed channel which opens outside the machine housing.
