ABSTRACT:
A valve system controls which air bags on a tractor trailer are in fluid communication with a pressurized air supply source. If one of the air bags develops a leak, an air bag may be taken out of fluid communication with the remaining air bags and pressurized air source. A pressure gauge monitors the air pressure within the valve system and air bags. A dump valve allows the air pressure within the system to be decreased.
