ABSTRACT:
An oscillating vane rotary pump or motor. The pump or motor comprises a cylinder with a pair of co-axial rotors journaled in the cylinder. Each of the rotors defines a pair of spaced apart sector shaped vanes with the vanes of one rotor intermediately juxtaposed with the vanes of the other. A power shaft journaled in the cylinder includes a quill or sleeve shaft which drivingly engages the co-axial rotor shafts. Inlet ports and outlet or exhaust ports are provided in the cylinder for receiving and exhausting pressure fluid. Operative coupling means are provided for oscillating the rotors and vanes with respect to each other as the rotors rotate with respect to the cylinder. A drive pin extends through the rotor shaft and power shaft quill. An elongated slot is provided in the quill to permit axial reciprocation of the pin as the power shaft rotates. Helical slots are defined in each of the co-axial rotor shafts, one of the helical slots having a left-hand curve and the other having a right-hand curve. Cam rollers on extending ends of the drive pin ride in a cam track defined by cam surfaces on opposed annular cam sleeves secured within the cylinder. Relative rotation between the cylinder and rotor causes the pin to reciprocate axially and thereby effects rotary oscillation between the rotor vanes as the entire rotor rotates relative to the cylinder.
