variable displacement vane pump working

  • Rotary vane pump - Wikipedia

    A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity In some cases these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotat It was invented by Charles C Barnes of Sackville, New Brunswick, who patented it on June 16, 1874
