Abstract
A rotary pressure transfer device utilizes a multi-channel, generally cylindrical rotor () that revolves with its flat end faces juxtaposed with flat end surfaces of a pair of flanking end covers () in which inlet and outlet passageways are provided. The design is such that there are only oblique ramps () in the passageways on the high pressure side which create directional flow of liquid to cause rotor revolution in the desired direction. Passageways () on the low pressure side may be shaped so that there is essentially axial or longitudinal flow entry and discharge of liquid between the channels and the passageways, or passageways () may be constructed to create directional flow that slightly retards rotor revolution in such desired direction.
