Abstract
Systems for monitoring and adjusting the air pressure in a rotating wheel in air-tight connection with a non-rotating axle. In one embodiment, a non-rotating tank air pressure system is separated from a wheel air pressure system by a fill-purge valve. Manipulating the fill-purge valve changes the air pressure in the wheel air pressure system, while the wheel may be rotating, and the change in air pressure is monitored by a gauge.
Claims16
A system for adjusting gas pressure in a wheel tire comprising:
- a compressed gas tank comprising compressed gas at a pressure higher than atmospheric pressure;
- a hollow axle with an open end and a closed end, at least one hollow axle hole and an outer circumference;
- a fill-purge valve in air flow connection with the compressed gas tank;
- an axle air-port in air flow connection with the fill-purge valve and with the open end of the hollow axle;
- an axle sheath having an inner circumference at least partially around the outer circumference of the hollow axle and having at least one axle sheath hole in air flow connection with the at least one hollow axle hole;
- at least two static o-rings between the axle sheath and the hollow axle, with the at least one axle sheath hole and the at least one hollow axle hole located between the at least two static o-rings;
- at least two dynamic seals each having a inner lip around an outer circumference of the axle sheath, with the at least one axle sheath hole and the at least one hollow axle hole located between the at least two dynamic seals;
- a hub having an inner circumference in air-tight connection with the at least two dynamic seals and having;
- a radial trough in the hub inner circumference, with the radial trough in air flow connection with the at least one axle sheath hole;
- and
- a hub air-port in air flow connection with the radial trough and with a wheel tire.

A method of monitoring and adjusting air pressure in a wheel tire, comprising:
- monitoring a pressure gauge that measures pressure in a wheel tire;
- manipulating a fill-purge valve to transfer compressed gas through at least one hollow axle hole and through at least one axle sheath hole which are between at least two dynamic seals with each of the at least two dynamic seals having an inner lip around an outer circumference of an axle sheath which has an inner circumference at least partially around an outer circumference of a hollow axle with at least two static o-rings between the outer circumference of the hollow axle and an inner circumference of the axle sheath;
- and
- ceasing manipulation of the fill-purge valve when the pressure gauge is at a desired pressure.
