Abstract
In liquid ring gas pumps of the type having a rotor rotatably mounted in a stationary housing for forming a quantity of pumping liquid into a recirculating ring inside the housing, fluid friction loss between the liquid and the housing is reduced by shaping the surface of the housing which is in contact with the liquid ring radially outside the rotor so as to minimize or at least substantially reduce the area of that surface.
