Abstract

A liquid ring pump includes an external housing enclosing a volume including a lower fluid reservoir. A rotatable inner housing is within the volume of the external housing, the inner housing enclosing an inner fluid chamber. A pitot tube provides fluid communication between the lower fluid reservoir and the inner fluid chamber. The housings and pitot tube are adapted so that when the inner housing rotates, fluid flows from the lower fluid reservoir through the pitot tube into the inner fluid chamber to develop a liquid ring within the inner fluid chamber such that an inner radial wall of the liquid ring is just radially outward from a point where the pitot tube enters the inner fluid chamber.
