    摘要: A variable displacement vane pump has an inner peripheral face of a cam ring formed so that in a maximum eccentric state, a radius vector gradually shortens according to the rotation of a rotor in an area from a starting point of a first seal interval to an intermediate point of the first seal interval and an area from an intermediate point of a second seal interval to an end point of the second seal interval. The inner peripheral face of the cam ring is formed so that in a minimum eccentric state, the radius vector is substantially fixed or gradually lengthens according to the rotation of the rotor in other areas.
