Abstract
An apparatus for and a method of sensing fluid pressure of a tire and the fluid supply of a tire pressure management system maintaining same, with a central sensor and which requires the control of only two valves. The apparatus for sensing fluid pressure of a tire and the fluid supply of a tire pressure management system maintaining same, includes a sensor disposed so as to be selectably in fluid communication with one or both of: a first valve, operable from an open position through a closed position, for respectively promoting and prohibiting fluid flow from the fluid supply, and a second valve, operable from an open position through a closed position, for respectively promoting and prohibiting fluid flow to or from the tire. The method of sensing fluid pressure of a tire and the fluid supply of a tire pressure management system maintaining same includes disposing a sensor so as to be selectably in fluid communication with one or both of: a first valve, operable from an open position through a closed position, for respectively promoting and prohibiting fluid flow through a supply passage from the fluid supply, and a second valve, operable from an open position through a closed p…
