PROBLEM TO BE SOLVED: To reduce electric current supplied when a control valve is open in accordance with a temperature condition.SOLUTION: An air suspension device includes: an air compressor 1; four air springs 9; an air supply/drainage valve 12 mounted between the air compressor 1 and each of the air springs 9, and driven by a solenoid 12A; and a controller 17 controlling open/close of the supply/drainage valve 12. The supply/drainage valve 12 is provided with temperature detection means 13 detecting the temperature of a solenoid 12A. The temperature detection means 13 outputs the temperature detection signals toward the controller 17. The controller 17 determines an electric current value necessary to open/close the supply/discharge valve 12 on the basis of the temperature of the solenoid 12A of the supply/discharge valve 12.SELECTED DRAWING: Figure 6 |
