Abstract: front page image
(EN)This vane pump (100) comprises a rotor (20), a plurality of vanes (30), a cam ring (40), pump chambers (41), and a center port (45). The center port (45) has: an inner opening (46) open to the inner peripheral cam surface (40a) of the cam ring (40); and an outer opening (47) open to the outer peripheral surface (40d) of the cam ring (40). The starting end (46a) of the inner opening (46) is located in front of a first imaginary line (I1) in the direction of rotation, the first imaginary line (I1) connecting the starting end (47a) of the outer opening (47) and the center (C) of rotation of the rotor (20).
