ABSTRACT:
There is provided a positive displacement hydraulic rotator unit capable of operating in either direction of rotation. The rotator unit comprises a housing defining a substantially cylindrical internal chamber centered about a first central axis, and a rotor within the chamber. The rotor is rotatably mounted about a second axis, parallel to the first axis but radially displaced. There are intake and exhaust openings into the chamber, angularly displaced about and through the cylindrical surface. The rotor comprises a substantially rigid core having at least three radially extending, centrally interconnected channels for slidably holding rigid elongated blades. The blades are in turn interconnected by a rigid member so that the rigid member and the blades rotate and move radially as a single unit. The radially outwardmost end of each blade forms a seal with the cylindrical surface and the sides of each blade forms seals with the end walls of the chamber, so as to divide the internal chamber into sealed sections. The blades and the inlet and exhaust openings are so placed that the two openings are always separated by at least one rotor blade. A shaft for providing mechanical energy is secured to the center of the rotor core. The rotator unit can most effectively be used as part of a closed loop hydraulic system, for example, for providing the driving force for a wheeled vehicle.
