Abstract
A rotary vane type motor, compressor or pump in which an eccentrically mounted rotor having sliding vanes rotates within a stationary main housing or stator. The stator is in turn defined by a pair of opposed shells, each shell essentially being a half cylinder such that the internal working surface of the stator against which the vanes move, forms essentially two opposed and identical circular paths or segments. The movement path of the vanes may be further controlled by rollers affixed thereto and adapted to engage a free idling race ring mounted inside of the hollow rotor and supported by means of a stationary crankshaft. In this added way the vanes pass the internal working surface of the stator without contact at a controlled clearance and the centrifugal force of the vanes acting against the stator housing is eliminated such that increased efficiency and operation at substantially higher speeds is accomplished.
