PURPOSE:To permit the certain operation of a transmission for car by stabilizing the oil pressure by swing-shifting the cam ring of a variable capacity vane pump according to the oil amount demanded according to the load. CONSTITUTION:The cam ring 9 of a variable capacity vane pump 1 is axially supported in swingable ways by a pin 7, and the increase pressure and the decrease pressure act onto the both sides, having the line passing through the pin 7 and the center of the cam ring as boundary line. When the accelerator of a car is kick-down-operated, a throttle valve 25 and a kick-down plug 26 are operated to supply the increase pressure into an oil chamber 15, and the discharge amount of the pump is increased by increasing the amount of eccentricity of the cam ring 9. Therefore, pressurized oil is supplied free from delay into the transmission of the car, and the transmission can be operated certainly. |
