Hydraulic Pump Vane

Hydraulic pump vane and rotor, stator and waist into, the new structure of oil outlet of the pump core components. Blade mounted in the rotor, when the rotor is driven by the prime mover is rotated, the blades being thrown under the effect of centrifugal force, the inner stator surface moving along a curve, to maintain contact with the inner surface of the stator, between the blade tips and the stator is formed reliable seal.
Eccentric rotor and stator installation, as the rotor turns, between the stator and blade in the formation of the change of volume increase and a decrease in volume.
The stator is provided with the oil port, the use of the valve plate into the oil chamber and the oil chamber separated. Valve plate mounted on the stator, the rotor blades and components side, the suction port located on the site of the volume increases, the oil port is located at the site of the volume is reduced, all the oil through the port plate into and out of the pumping mechanism.
