ABSTRACT:
A basic rotary vane mechanical power system, suitable for engines, pumps, compressors and the like, having an enclosed chamber housing a rotating hub plate, with the hub plate assembly supporting a plurality of spaced apart rotary vanes rotating on their own separate shafts and carried in a circular path by the hub plate assembly. The rotation of the hub plate assembly imparts rotation of the plurality of vanes within the enclosed, tight-fitting chamber, the angular rotation of the vanes being one-half of the angular velocity at which the hub plate and power shaft are rotating and transmitting power, or some other suitable ratio. During rotation of the vanes, the volume between the vanes increases and decreases, so that the volume of fluid within that space is contracted or expanded to drive the system or provide a source of power to the system or the working fluid. The volume of fluid between the vanes is determined principally by the thickness of the vane on one side of this circular path and also determined by the width of the vane where the chamber reaches its maximum width.
