摘要： A diagnostic method for sensing system faults in an on-board CTIS (10) for measuring and controlling the inflation pressure of an inflatable tire (12/14), said CTIS measuring inflation pressure of said tire by fluidly connecting the interior pressurized chamber of said tire to means (22) associated with a conduit (20) for causing said conduit to assume a pressure equal to tire pressure and then sensing the pressure in said conduit; said CTIS having a steady state condition during which said conduit is isolated from the interior pressurized chamber of said tire and is vented to atmospheric pressure, said method characterized by:
causing said CTIS to assume the steady state condition thereof;
sensing the pressurization in said conduit during steady state conditions;
comparing said sensed pressure in said conduit to a predetermined reference range of pressures; and, if said sensed pressure is not within said reference range, preventing further control or measurements of the pressurizing of said tire.

摘要： An improved wheel end valve assembly (11) for a Central Tire Inflation System have a single connection (72) to a tire chamber (74) and a single connection (66) to a source of pressurized fluid, which requires no venting other than through a single supply conduit (62), is effective in response to pressurization and venting of the supply conduit (62) to open and close communication to a tire (12), and to isolate the tire (12) 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 an elastomeric disk shaped, one way valve (300) having an orifice (316) formed therein which is self cleaning when the valve is actuated.

摘要： An air circuit for a central tire inflation system having a relief valve (158) in the air circuit to provide the necessary pressure drop for deflation and having make up air from a source (S) bleed into the air circuit via one of two normally closed solenoid actuated valves (164, 174). The make up air is connected via a small orifice (214) when a solenoid (192) associated with a deflate valve (164) or shut off valve (174) is energized.

摘要： A central tire inflation system (10) comprising a pressure relief valve (180) fluidly interposed control means (142, 156, 164,154,172) and a tire valve assembly (56, 58) is provided. The control valve assembly is effective to selectively pressurize or exhaust a first conduit (170) connected to a first port (178) of the pressure relief valve, a second conduit (50, 52) extends from a third port (184) of the pressure relief valve to the tire valve assembly and a second port (182) is connected to atmosphere. The pressure relief valve is effective to establish fluid communication between said first and second ports thereof when the pressure in said first conduit exceeds the pressure in said second conduit and to establish fluid communication between the second conduit and the exhaust port (182) if the pressure in said second conduit exceeds the pressure in said first conduit. The tire valve assembly is fluidly connected to a third conduit (68) fluidly connected to the interior pressurized chamber (74) of an inflatable tire (12). The tire valve assembly is effective in response to pressurization of the second conduit above a first reference pressure and pressurization of said interior chamber above a minimum tire pressure reference value to establish fluid flow between said second and third conduits.

摘要： 57 A tire valve assembly (56, 58 or 300) for a central tire inflation system (10) effective to automatically isolate a tire (12) pressurized to less than a predetermined minimum pressure from the remainder of the system is provided. The tire valve assembly includes a control valve (58) and a low tire pressure shut-off valve (56) which are connected to a selectively pressurized and vented conduit (52) and to a conduit (68) fluidly communicating with the interior pressurized chamber (74) of the tire. A single selectively pressurized and vented conduit (52) operates the control valve and ; provides the sole connection of the assembly to pressurized . fluid and/or to venting to atmosphere required for system operation other than for initial inflation of the tires to the predetermined minimum pressure thereof. The assembly may comprise a single valve body (302) having only a first , (304) and a second (306) fluid connection from the exterior to the interior thereof. As the valve assembly (300) is provided ¦ in a single valve body and requires no venting to atmosphere other than through the first port (304), the valve assembly may be mounted within the interior pressurized tire chamber (74) such as within a pocket (404) provided in an annular sleeve type bead lock (400).
