Abstract
An improved wheel end valve assembly for a Central Tire Inflation System having a single connection to the tire chamber and a single connection to the source of pressurized fluid, which requires no venting other than through the single supply conduit, is effective in response to pressurization and venting of the supply conduit to open and close communication to the tire, and to isolate the tire if inflation pressure thereof falls below a minimum reference pressure. A controlled bleed of air between the control circuit and the isolation circuit is provided by a elastomeric disk shaped, one way valve having an orifice formed therein which is self cleaning when the valve is actuated.
