プ。A shaft 3 of a motor rotor 2 in a motor chamber 1 is rotatably supported, and a rotor 4 fixed to the shaft and a vane 6 disposed in a vane groove 5 of the rotor are connected to a suction plate 7. Disposed within a pump chamber 10 formed by a pump ring 8 and a discharge plate 9,
In a motor-type vane pump that transports fluid from a motor chamber 1 to a pump chamber 10 by rotation of a motor rotor 2,
A groove 12 provided on the side surface of the rotor 4 on the suction plate 7 independently from the shaft hole 11 and a groove 14 provided on the side surface of the rotor 4 on the discharge plate 9 independently from the shaft hole 13 are communicated via the vane groove 5. At the same time, the shaft hole 15 formed by the shaft hole 13 of the discharge plate 9 and the motor chamber 1 are communicated along the shaft 3 and independently from the '4412.14, and acts on the rotor 4 and the shaft 3. A motor-type vane pump that uses low pressure to offset the axial fluid force.
