  • Fluid stream driven wobble plate motor
    Patent number: 9551223
    Abstract: Several embodiments of a wobble plate motor include a disc mounted on a bent shaft. Driving the wobble plate so it revolves on a flat base causes the bent shaft to rotate and drive a generator or other work consumer. The wobble plate may be driven by a fluid stream impinging on the plate or by a blade assembly in a path of fluid movement. In one embodiment of a bladed motor, a shroud may direct the fluid stream so it more efficiently cooperates with the blade assembly.
    Type: Grant

  • Wobble plate motor
    Patent number: 8545176
    Abstract: A wobble plate motor comprises a rotatable shaft having a bent end rigid with the shaft and an inclined plate journalled on the bent end. When only one side of the inclined plate is directly subjected to high pressure, the plate rolls on a base in the manner of a spinning coin as it decays, i.e. as its spin rate falls to a value where the coin is inclined to the axis of rotation. As the plate rotates, torque is generated on the rotatable shaft so the shaft may drive a work consumer such as a generator, pump or compressor.
