Abstract
A positive displacement pump comprising a casing having an interior chamber and an inlet and an outlet oppositely spaced within the chamber. A rotor with a cylindrical outer surface is secured in offset position within the chamber. An end disk is secured to each end of the rotor. Three planar vanes are provided, each having sides and inner and outer edges. The sides of the vanes are seated within the end disk slots. The outer edges of the vanes are in constant contact with the side wall of the chamber. The inner edges of the vanes are constantly movably seated in the rotor slots during operation of the pump. The slots in the rotor within which the vanes are seated are formed along a chord when the rotor is viewed in lateral cross section and are orientated so that their planes lie at 60° angles to the planes of adjacent slots.
