A height control pneumatic circuit of air suspension for a vehicle is provided to allow a compressed air flow for controlling vehicle height to be accomplished by one solenoid valve and one pilot valve, thereby simplifying pneumatic lines and preventing a locking phenomenon of the valves. A height control pneumatic circuit of air suspension for a vehicle comprises a pneumatic supply line(2), a first pneumatic discharge line(10), a second pneumatic discharge line(12), a supply pneumatic applying line(9), a discharge pneumatic applying line(14), and a controller(8) for controlling a pneumatic source(1) and a direction control valve(7) to supply or discharge an air spring(3) with compressed air so as to control the vehicle height. The pneumatic supply line is provided thereon with first and second supply check valves(5,6) to accomplish one way flow paths. The direction control valve is a solenoid type valve. |
