Constant pressure pneumatic balancing tire inflation system

摘要

A constant pressure vehicle tire inflation system includes an air supply source. A first wheel valve is in fluid communication with a first tire of the vehicle, and a second wheel valve is in fluid communication with a second tire of the vehicle. A pneumatic conduit extends between and is in fluid communication with the air supply source and the wheel valves. At least a portion of the pneumatic conduit remains charged with air from at least one of the supply source and the tires. The system includes means for distributing air flow between the pneumatic conduit and the first and second wheel valves, in which the wheel valves and the means selectively maintain fluid communication between the first and second tires and the pneumatic conduit to provide pneumatic balancing between the tires, and the wheel valves provide emergency protection when a tire experiences significant pressure loss.

1. A constant pressure vehicle tire inflation system, comprising:
an air supply source; a first wheel valve being in fluid communication with a first tire of said vehicle; a second wheel valve being in fluid communication with a second tire of said vehicle; a pneumatic conduit extending between and being in fluid communication with said air supply source and said wheel valves, at least a portion of said pneumatic conduit remaining charged with air from at least one of said supply source and said tires; and means for distributing air flow between said pneumatic conduit and said first and second wheel valves, whereby the wheel valves and said means selectively maintain fluid communication and flow between said first and second tires and the pneumatic conduit to provide pneumatic balancing between the first and second tires.
