PURPOSE:To control the pressure of respective tires automatically, individually and steplessly by interposing a plurality of tanks, regulating valves and relay valves between a compressor used in a braking device and a plurality of tires. CONSTITUTION:A compressor 3 is driven by an engine to force-feed air through a driver 112, a purge tank 113 and a check valve 116 to a tank 115 for braking. A brake valve 119 is operated and a brake device 111 is operated by air in the tank 115 for braking. On the other hand, the air in the purge tank 113 is force-fed to each tank 4 through a filter 9 and a check valve 8. The air in each tank 4 is force-fed to each regulating valve 5 and each relay valve 6 through each check valve 15 and each switching valve 14. According to the air pressure of each regulating valve 5 and the air pressure of each tire 2, air between each tank 4 and each tire 2 is supplied and discharged by each relay valve 6 to automatically control the air pressure of each tire 2. |
