ABSTRACT:
A rotary vane pump comprising an inner rotor and an outer rotor which rotate together about eccentric axes. A pair of support shafts is attached to the inner rotor and are rotatably mounted for rotation of the inner rotor. At least one of the support shafts is hollow and serves as a fluid conduit. The outer rotor and the inner rotor are provided with ports at the ends thereof for flow of fluid into the inner rotor. The relative dimensions of the rotors are such that a chamber is formed between the rotors. A vane is attached to the outer rotor and slidably extends into a slot in the inner rotor. The vane divides the chamber into intake and outlet portions. Fluid flows from the inner rotor into the chamber between the rotors, and fluid flows from the chamber into a fluid conduit formed by the hollow support shaft. The rotary vane pump is adapted to pump fluids, such as gases and liquids, separately or in combination. The rotary vane pump includes structure for introducing and circulating a lubricant within the pump.
