Abstract:
A turbine for flowing fluids, especially a turbine having a vertical power output shaft and having several wings projecting radially out from the power output shaft, which wings are rotatable over an angle of about 90Â° about horizontal swinging shafts extending along a trailing edge of the wing as seen in a flow direction of the flowing fluid, so that the wings, in an operative, first position are positioned at right angle to the flow direction of the flowing fluid and in a non-operative, second position are positioned horizontally, or nearly horizontally, characterizedin that each wing has a body in the form of a flat wing plate which, at an radial outer end thereof, is formed with a fin like wing point which fin like wing point is bent down so that an outer fin like part thereof is located underneath a main plane of the wing plate for the purpose of catching, at a very early stage of an operation cycle, flowing fluid passing by the outer fin like part and thereby initiating a rotation downwards of the wing to a position at right angle to the flow direction of the flowing fluid, and in that the turbine is arranged to be mounted, in the operative position, with the main plane of the wings closely above the flowing fluid.
