An improved wheel end valve assembly for a central tire inflation system having a single connection to a tire chamber and a single supply connection to a source of pressurized fluid, which requires no venting other than through the ingle supply connection, is effective in response to pressurization and venting of the single supply connection to open and close communication to the tire chamber, a second valve means to isolate the tire chamber if inflation pressure thereof falls below a minimum reference pressure, and a third valve means. The third valve means comprises a controlled bleed of air between the single supply connection and an isolation circuit by an elastomeric one way valve. |
