ABSTRACT:
A motor for converting fluid pressure to rotational motivation, and pump for moving fluid, is provided. The motor/pump includes a drum provided within a cylindrical cavity defined by a housing. Vane assemblies are provided which extend through the inner drum, and are actuated to extend and retract through their operable coupling to a cam provided within the inner drum. As the inner drum rotates, the vanes extend and retract, alternately increasing and decreasing their drag coefficient, causing pressurized fluid admitted into the interior to drive the vanes and inner drum in a single direction. Alternatively, a power source may be coupled to the motor to drive the motor, thereby causing it to act as a pump for moving fluid from one location to another.
