ABSTRACT:
A rotary vane pump comprising an inner rotor and an outer rotor which rotate about eccentric axes. A pair of hollow support shafts rotatably support the inner rotor and serve as passages for flow of fluid to and from the inner rotor. Passages within the inner rotor are in fluid communication with the passages which extend through the support shafts. The relative dimensions of the inner rotor and outer rotor are such that a chamber is formed between the inner rotor and outer rotor. 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. A check-valve is positioned to control flow of fluid in the outlet portion of the inner rotor.
