摘要： PROBLEM TO BE SOLVED: To provide a variable displacement vane pump wherein oscillation resulting from discharge quantity is suppressed, and response at the time of increase in the discharge quantity is improved. SOLUTION: As a rotor 2 is rotated, vanes 3 are slidably moved on the inner circumferential surface of a cam ring 4. The cam ring 4 is eccentric with respect to the rotor 2 by pressure difference between a first fluid-pressure chamber 33 and a second fluid-pressure chamber 34. By a control valve 21, which is operated in response to discharge pressure of the pump, pressures of the working fluid in the first fluid chamber 33 and the second fluid chamber 34 are controlled so that as the rotation speed of the rotor 2 is increased, eccentricity of the cam ring 4 with respect to the rotor 2 is reduced. A flow control means 22e controls a discharge rate of the working fluid in the second fluid-pressure chamber 34, in the situation where the working fluid is supplied to the first fluid pressure chamber 33, and is discharged from the second fluid pressure chamber 34 to reduce the eccentricity of the cam ring 4 with respect to the rotor 2.
