ABSTRACT:
An apparatus for generating and/or measuring fluid flow and/or generating power from fluid flow comprises two combinations of a cylindrical cavity and a divider member rotatably disposed in the cylindrical cavity about an axis of rotation parallel and eccentric to the geometrical central axis of the cylindrical cavity, which divider member extends across the cylindrical cavity on a plane including the axis of rotation in all instances of rotating movement thereof, and a rotary motion coupling means coupling rotating motions of the two divider members in such a way that a phase angle difference of ninety degrees in the rotating motion between the two divider members is maintained, wherein fluid moving through the two cylindrical cavities and crossing each plane including the geometrical central axis and the axis of rotation in each of the two cylindrical cavities relates to rotating motion of the two divider members.
