Abstract (en)

[origin: WO8604110A1] A power conversion device which can efficiently convert between fluid pressure and rotary motion. The device includes a piston plate (70), which is surrounded by an array of pressure chambers (76, 78, 80, 82) and engageable with a shaft (20) and its accompanying gear assembly (24). Manifold networks (30, 40) act as valves to control the sequential pressurization and depressurization of the pressure chambers so as to produce orbital movement of the piston plate about the shaft, as though it were floating on a cushion of air.
