Abstract:

A valve is disclosed for use in a system and process for controlling vehicle loading on a multi-axle vehicle and improving maneuverability. The valve partially exhausts air from an axle air bag when the vehicle is maneuvering at slow speed, reduces the load on the axle, and thus reduces damaging forces that affect tire wear and suspension component wear. The valve is a normally open, pilot operated valve that delivers supply air pressure upon receiving a sustained air pressure input of a pilot signal. Using an inversion function, the valve then dumps the delivery pressure through a high capacity exhaust upon receiving the pressure input of a secondary control signal. The hold function of the valve traps a reduced amount of delivery air pressure by closing the exhaust valve, and the hold function is actuated at a predetermined delivery pressure to trap a volume of air in the associated air suspension system until the valve member is returned to a supply position.
