Abstract
When one chamber of vane pump is located at an end of a discharge process and is compressed at maximum, pressure in the chamber is higher than the discharge pressure of the pump. Vanes are supported in slits of a rotor. A passage connecting the one chamber and inner sides of the vanes in the slits supplies pressure to push the vanes onto an inner surface of a cam-ring of the pump.
