Abstract: A wind power conversion turbine motor has a body supported to rotate about a vertical axis and carrying a plurality of substantially upright vanes substantially spaced from the vertical axis and circumferentially spaced from one another so that wind thrusting propulsively against outer sides of the vanes can move across the space circumscribed by the vanes and thrust propulsively against inner sides of the vanes on leaving the space, thereby attaining dual power advantage from substantially all wind that strikes the turbine. Each of the plurality of vanes is pivotally carried on the body, with a control means to maintain a substantially constant vane angle of attack to a relative wind vector.

Abstract: In a pump or motor assembly having telescoped slidably relatively rotative surfaces whereby one of the members supports the other member for relative rotation and one of the members has passage means for hydraulic pressure fluid. Hydraulic bearing means between the surfaces in communication with the pressure fluid passage have distribution of hydraulic pressure fluid to the bearing means controlled by valve means to improve efficiency of the hydraulic bearing means to counteract off-center forces. In a preferred arrangement the bearing means comprise circumferentially spaced pockets in one of the relatively rotative surfaces, and the valve means control distribution of hydraulic pressure fluid to the pockets by modulating lowered pressure in any of the pockets.

Abstract: Radial piston pump or motor has within its housing a stationary pintle valve, an external shaft connected to a rotating spider of which are mounted pressure balanced pivotal cylinders. Rigid piston - shoe assemblies engage the cylinders and ride on a cylindrical raceway the eccentricity of which is adjustable for stroke. Balanced annular sealing is provided between the pivotal cylinders and arcuately surfaced pockets therefor in the rotating spider/rotor.
