ンポンプ。 A rotor connected to a rotating shaft so as to be movable in the axial direction and rotate integrally therewith is disposed within the pump housing, and a plurality of vanes are provided on the outer periphery of the rotor, and the tips of the vanes are provided outside of the rotor. While making contact with the inner cam surface of the cam ring,
Housing walls are closely opposed to both end faces of the rotor and each of the vanes to form a closed pump chamber between each of the vanes, and fluid is sequentially sucked into each pump chamber from the suction port and discharged from each pump chamber. 1. A vane pump that sequentially compresses and discharges fluid to a port, characterized in that magnetized regions of the same polarity are formed on each end face of the rotor and on each of the housing wall portions facing thereto.
