<p>A rotary fluid energy translating device of the sliding vane type useful as a pump or motor comprising a pressure contained vane unit assembly (20) adapted to be submerged in a body of liquid. The pressure contained vane unit assembly comprises a pair of support plates (30,31), a cam ring (32) interposed between the support plates, a rotor (60) rotatably mounted in the cam ring (32) and having a plurality of circumferentially extending vanes (61) adapted to engage the contour of the cam ring (32) and a flexible plate (33,34) interposed between the cam ring and each of the support plates. Each support plate (30,31) includes a hub portion (37,49) spaced from its respective flexible plate. The assembly (20) is clamped together with a clamping force in excess of the hydrostatic forces within the assembly. One of the support plates (30) has an axial opening for insertion of a drive shaft (23) into driving connection with the rotor (60) and the other of the support plates (31) has an axial liquid passage (41). Each support plate (30,31) includes radial liquid passages (35,44) defined by a groove at the juncture with its associated flexible plate. When used as a pump, the assembly is submerged in a liquid and the rotor is driven to provide a pump, the radial passages (35,44) provide inlet passages and the axial passage provides an outlet. The pressure contained vane unit assembly can also be used as a hydraulic motor by utilizing the axial passage as an inlet from a pressurized source such that the radial passages function as outlets for the fluid after its energy has been dissipated by rotating the rotor and vanes. <IMAGE></p> |
