  A simple vane pump includes a circular rotor that rotates in a larger circular cavity. The centers of the two circles are offset, causing eccentricity. The blades are allowed to slide in and out of the rotor and are sealed at all edges to form a blade chamber to complete the pumping work. On the intake side of the pump, the volume of the vane cavity is increasing. These increasing volume vane cavities are filled with fluid driven by inlet pressure. The inlet pressure is actually the pressure from the pumping system, usually just atmospheric pressure. On the discharge side of the pump, the volume of the vane cavity decreases, forcing fluid out of the pump. The function of the blade is to expel the same volume of fluid with each rotation.
  
  
  Generally, the pump mechanism includes a...    less
