System and method for decreasing tire pressure
First Claim
1. A method for decreasing tire pressure, comprising:
- providing a wheel assembly which defines a chamber that houses a pressurized fluid;
providing a wheel valve assembly in fluid communication with the chamber, the wheel valve assembly operable between an open position and a closed position and comprising an area having a first flow capacity;
providing a variable area valve assembly selectively in fluid communication with the wheel valve assembly, the variable area valve assembly comprising an area formed in a perforation that has a second flow capacity, the second flow capacity being less than the first flow capacity; and
selecting a target tire pressure;
wherein if a pressure of the pressurized fluid in the chamber is greater than the target tire pressure, then decreasing the pressure of the pressurized fluid in the chamber by directing a flow of pressurized fluid from the wheel assembly through the wheel valve assembly and the variable area valve assembly.

Abstract
A method for decreasing tire pressure includes providing a wheel assembly which defines a chamber that houses a pressurized fluid. A wheel valve assembly is provided in fluid communication with the chamber. The wheel valve assembly is operable between an open position and a closed position and includes an area having a first flow capacity. A variable area valve assembly is provided and is selectively in fluid communication with the wheel valve assembly. The variable area valve assembly includes an area formed in a perforation that has a second flow capacity. The second flow capacity is less than the first flow capacity. A target tire pressure is selected. If a pressure of the pressurized fluid in the chamber is greater than the target tire pressure, then the pressure of the pressurized fluid in the chamber is decreased.
