  • Air regulating system for wheels
    Patent number: 6533010
    Abstract: An air pressure regulating system mounted within a wheel and tire assembly. It primarily includes a temperature sensor and a compressor assembly having a compression chamber and valves. Utilizing centrifugal forces from the rotation of a wheel and tire assembly, air may flow into and out of a tire to automatically maintain the pressure inside a tire relatively constant over a given temperature range. When the pressurized air in the compression chamber is greater than the pressurized air in the tire, the pressurized air in compression chamber flows into the tire. When the pressurized air in the tire is greater than the pressurized air in the compression chamber, the pressurized air in the tire flows into the compression chamber. When the pressurized air in the compression chamber is equal to the pressurized air in the tire, it is in equilibrium, and no air flow occurs.
