Abstract

PURPOSE:To prevent the fall in the speed of the increase in the height of a vehicle, by providing a solenoid valve and a control circuit to disconnect a pressure accumulator from the air chamber of a suspension unit and the discharge port of an air compressor when the pressure of the accumulator is lower than a prescribed level at the time of energizing for increasing the vehicle height. CONSTITUTION:When a compressor 203 is driven, a solenoid valve 310 is opened to store pressure in an accumulator 330. When a solenoid valve 330 is opened, a suspension unit 400 is operated to increase the height of a vehicle. The pressure in the accumulator 330 is found out by a pressure detection switch 340. When the pressure is higher than a prescribed level, the switch 340 is off. When the pressure is not higher than the level, the switch is on. When the pressure is higher than the prescribed level, a timing unit 140 has a high output level. When the pressure is not higher than the prescribed level, the timing unit 140 has a low output level. when the pressure switch 340 is on and the timing circuit 140 has the low output level at the time of the opening of the solenoid valve 310 by a vehicle height increasing signal generated by a counter CO2, the output level (i) of a gate AN1 becomes low to close the solenoid valve 310 to supply compressed air 203 only to the suspension unit 400. For that reason, the speed of the increase in the height of the vehicle is prevented from falling.
