Abstract
An automatic tire inflation system with a booster pump actuated by the compressed air supply on the truck-trailer to pump the air pressure to a higher output pressure to supply air to tires that may require a higher inflation pressure than the truck-trailer system provides. In addition, a surge protection valve and a pressure relief valve are provided in the system to provide proper operation of the system.
Claims16
In an air inflation system for a vehicle having at least one axle with at least one wheel having a pneumatic tire at each end of the axle, said vehicle having an air supply, an air connection including a rotary connection between the air supply and the tires, the improvement of means for increasing the air pressure from the air supply to the tires comprising,
- an air booster pump having an inlet and an outlet, said inlet connected to the air supply and said outlet connected to the rotary connection and the tires, said pump increasing the air pressure from the air supply.
In an air inflation system for a vehicle having at least one axle with at least one wheel having a pneumatic tire at each end of the axle, said vehicle having an air supply, an air connection between the air supply and the tires including an air passageway inside the axle and a rotary air connection in communication with the passageway, a pressure control valve controlling the pressure in the air connection, a sensor connected to the air connection for detecting an air leak in a tire, the improvement of means for increasing the air pressure from the air supply to the tires comprising,
- an air booster pump having an inlet and an outlet, said inlet connected to the air supply and said outlet connected to the air connection to the tires, said pump increasing the air pressure from the air supply.
