  • a disadvantage of this device is the need to orient the inlet directly "against" the wave, and this is due to energy consumption, comparable or exceeding the expected power of the device.
  • the vertical placement of the axis of rotation of the impeller does not allow the use of gravitational forces arising from the reciprocating movement of water masses in the surface layers of the reservoir.

  • each working chamber can be made separately from two or more parts that have the possibility of compact folding into each other. Modules assembled at the operation site are attached coaxially to each other, either to the shaft, the axle or any supporting structure. To transfer the resulting rotational motion to a generator, pump or other device to perform useful work, an arbitrary design of a drive shaft is used, which is not shown in the figures.

  • Phase 2 shown in Fig.Z: Lowering the wave and relative
  • the overall diameter of the module was 1200 mm, the section of the working chambers - 300x300mm.
  • the module consists of three working chambers, closed from the rear with respect to the direction of rotation of the side ventilation grilles with movable louvers.
  • the blinds did not provide such tightness as the valve.
  • they had a much lower hydraulic resistance, and minor losses due to fluid leakage were more than offset by the positive torque that the other working chambers created.
