Patent ID: 8297923

Claim:
A device for utilizing kinetic energy of flowing water with several pressure surfaces rotating around a rotor axle, the pressure surfaces being pivotable around axles arranged parallel to and spaced around the rotor axle, the pressure surfaces being attached to the pivot axles in a pendulum-like manner, and stop elements for the pressure surfaces being arranged in radial planes between the pivot axles and the rotor axle, the pivot axle of the pressure surfaces being attached by their ends to support disks radially directed towards the rotor axle and the support disks being located at the ends of the rotor axle and attached thereto, such that the pivot axles of the pressure surfaces remain parallel to and maintain a same spacing around the rotor axle during rotation of the device, the support disks being embodied in at least a double-walled manner, and additional surfaces distributed asymmetrically over a rotational circle and positioned crosswise to a direction of flow on the support disk and further comprising additional pressure surfaces arranged in planes of the pressure surfaces on sides facing away from the pressure surfaces with respect to the pivot axles, the additional pressure surfaces being structured to enlarge a leading surface area comprising the pressure surfaces and the additional pressure surfaces such that resistance of the pressure surfaces is increased with respect to the flowing water.
