INERTIA-CONTROLLED TIRE ISOLATION VALVE AND METHODS OF CONTROLLING TIRE INFLATION PRESSURES

摘要

Embodiments of the invention include methods and apparatus for adjusting the inflation pressure of a pneumatic tire. Particular methods include the step of arranging a tire in fluid communication with an inflation pressure source on a vehicle. Further steps may include arranging a rotational fluid passage between the tire and a vehicle axle and arranging along the rotational fluid passage an inertia valve that is biased in a closed arrangement while the valve is stationary or rotating below a desired speed about a rotational axis. Such methods may further include the steps of opening the inertia valve when the valve is rotating about the rotational axis at or above the desired speed and adjusting automatically the inflation pressure of the tire through the rotational fluid passage while the valve is open. Other embodiments comprise a system for adjusting the inflation pressure of a pneumatic tire.
