Rotating radial tube pump

Abstract

A rotating radial tube pump has a rotary portion and an extended inlet integral therewith, both of which rotate about a longitudinal axis through the extended inlet. The rotary portion has a traverse passageway with outlet openings at each end and an inlet opening into the transverse passageway. The extended inlet has a passageway traversing between an extended inlet opening and an extended outlet opening at each end of the passageway. The extended outlet opening communicates with the inlet opening of the passageway through the rotary portion. As the extended inlet and the rotary portion are rotated about a longitudinal axis through the extended inlet, the fluid flows into an inlet opening of the passageway traversing the extended inlet and then into the passageway traversing the rotary portion and then is expelled radially outward from outlet openings at each end of the passageway traversing the rotary portion.
