Patent ID: 7909076

Claim:
A tire pressure control system for a tire mounted to a wheel, comprising: a servo system mounted to the wheel and including a servo mechanically connected to a valve in fluid communication with gas inside the tire, the valve adapted for bleeding gas out of the tire and into the ambient atmosphere, a pressure sensor in fluid communication with the gas inside the tire, and a control circuit electrically connected to the servo and pressure sensor, the control circuit further including a signal receiving means and a memory for storing a commanded pressure signal, the control circuit actuating the servo to open the valve when the pressure sensor indicates a tire pressure of greater than the commanded pressure; the servo system further including a second servo mechanically connected to a fill valve that is in fluid communication with compressed gas inside a gas supply tank, the fill valve adapted for bleeding gas out of the gas supply tank and into the tire, the control circuit actuating the second servo to open the fill valve when the pressure sensor indicates a tire pressure of less than the commanded pressure; and a master control unit adapted to transfer the commanded pressure signal to the control circuit through a transmission means.
