Abstract: The invention relates to a device for utilisation of kinetic energy of a flowing medium comprising support members (2) mounted on a shaft (16) about an axis of rotation (6) and axially spaced apart from one another, and between which pressure surfaces (3) are disposed which are mounted pivotably about an axis (4) on the support members (2) and are supported on stops (5) which limit the pivoting movement, wherein a flow guiding means (7) designed as a buoyancy member is radially spaced from the pressure surfaces (3) and together with the pressure surfaces (3) forms a contour which narrows the flow cross-section between the pressure surfaces (3) and the flow guiding means (7).

Abstract: A device for utilizing the kinetic energy of flowing water with several pressure surfaces rotating around a common rotor axis. The pressure surfaces can be pivoted around axes arranged parallel to and spaced from the rotor axis, in particular for the production of energy from tidal currents of the sea. The pressure surfaces are attached to the pivot axes in a pendulum-like manner and stop elements for the pressure surfaces are arranged in the radial planes between the pivot axes and the rotor axis. The pivot axes of the pressure surfaces are attached by their ends to support disks radially directed towards the rotor axis. The support disks are located at the ends of the rotor axis. The support disks are embodied in at least a double-walled manner. Alternatively or additionally each pressure surface is embodied at least in a double-walled manner.
