PURPOSE:To enable car height to be promptly regulated as necessary, by mounting a flow selector valve to be interposed between a leveling valve and air springs, in the case of a vehicle mounting an air suspension. CONSTITUTION:When car height is low decreased for boarding and alighting, a device, if it switches a selector switch 22 to the side of an L terminal, intercepts air in a supply tank 7 by closing solenoid valves 20a, 20b. In this way, the device contracts air cylinders 21 forcedly actuating car height detecting levers 16 and leveling valves 4. Simultaneously the device, which opens a solenoid valve 13 by a signal of a control circuit 23 supplying compressed air from a supply tank 7 to flow selector valves 5 and opening then to a large bore flow, places the leveling valves 4 to communicate with air springs 9a-9d. Accordingly, the device, discharging a large amount of air in the air springs 9a-9d, rapidly low decreases the car height. By this constitution, the car height can be promptly regulated. |
