ABSTRACT:
A fluid flow driven engine comprising two counter-directionally rotating rotors rotatably mounted on a base which can be used to secure the fluid flow driven engine in the path of a flowing fluid, the rotors comprising cylindrical drums with a plurality of circumferentially spaced impellers projecting radially outward from each drum, the rotors being placed in closely spaced relation so as to define a fluid flow passageway between the drums. A housing having a venturi shaped or tapered inlet and outlet surrounds the rotors so that the inlet and outlet direct a flowing fluid through the passageway and the venturi shape increases the velocity of a fluid entering the passageway, extension plates being slidably mounted in the inlet and outlet portions of the housing to vary the cross-sectional areas of the inlet and outlet, thereby varying the velocity of a flowing fluid entering the passageway. The rotors are capable of rotating in either direction so that the direction of fluid flow through the engine may be reversed.
