Abstract
A solenoid valve system includes a supply solenoid valve, a plurality of exhaust solenoid valves, and a valve control section controlling opening and closing operation of the supply solenoid valve and the plurality of exhaust solenoid valves using PWM or PFM. The plurality of exhaust solenoid valves are disposed in parallel with each other. The supply solenoid valve and the plurality of exhaust solenoid valves have substantially identical flow rate characteristics. The number of the plurality of the exhaust solenoid valves is twice the number of the supply solenoid valve.
