Claims

[Scope of utility model registration request]

The rotor includes a rotor in which a plurality of vanes are inserted so as to be able to move in and out in the radial direction, a ring surrounding the rotor, and side plates arranged on both sides of the rotor, and is defined by the outer circumference of the rotor, the inner circumference of the ring, and the side plates in front and behind each vane. In the vane pump, the vane back pressure chamber of each vane has first and second pressure chambers formed on the back surface of each vane in the rotor, and the vane back pressure chamber of each vane is formed on the back surface of each vane in the rotor. first and second pressure chambers having first and second fluid resistances, respectively;
The vane pump is configured such that the pressure in the vane back pressure chamber can be changed by changing the first and second fluid resistances.
