ABSTRACT:
The invention is disclosed to variably control the amount of compressed air flowing per unit hour depending on the change in the level position of the wheel axles in a moving vehicle when the compressed air flows into air springs from the leveling valve or when the compressed air flows out of the air springs through the leveling valve, so as to make it possible to variably control the time to restore the status of the vehicle body depending on the level of rollings caused when the vehicle turns a corner, thereby achieving turning stability, higher response speed and steering.
