Abstract

An apparatus and method for mounting and inflating tires is described that is suitable for quickly sealing the beads of a tire to the rim of a wheel. The present invention delivers a high volume of pressurized air to an interior of a tire through a nozzle. The apparatus of the invention is particularly well suited for tire changing machines and tire mounting subsystems. The apparatus includes a tire changing station, an air supply controller, and a nozzle capable of delivering a high volume of pressurized fluid into an interior of a tire through a valve stem hole of the wheel rim.

Claims

1. A compressed air delivery apparatus of a tire mounting and inflation system, said air delivery apparatus comprising:

a nozzle having a main body and an air delivery conduit extending from main body, said main body adapted to couple to a pressurized air supply conduit;

a cable having a threaded adapter attached to a first end of said cable and wherein a portion of said cable extends through at least a portion of said air delivery conduit and wherein a portion of said cable extends out an open end of said air delivery conduit of said nozzle, and wherein said threaded adapter is adaptable to couple to a tire valve stem.

2. The air delivery apparatus as recited in claim 1, wherein said main body of said nozzle includes a first coupling to couple to a high volume pressurized air stream delivery hose.

3. The air delivery apparatus as recited in claim 2, wherein said main body of said nozzle further includes a second coupling to couple to an air return conduit.

4. The air delivery apparatus as recited in claim 1, wherein said main body includes a first passageway in fluid communication with a high volume pressurized air supply and a second air passageway in fluid communication with an air return conduit.

5. The air delivery apparatus as recited in claim 3, further including a pressure feedback conduit coupled to the main body and coupled in fluid communication with the air return conduit.

6. The air delivery apparatus as recited in claim 4, further including a pressure feedback sensing switch coupled in fluid communication to said air return conduit.

7. The air delivery apparatus as recited in claim 1, further including a pneumatic high volume air supply coupled to said pressurized air supply conduit and further including flow valve coupled to said nozzle.

8. The air delivery apparatus as recited in claim 1, wherein a second end of the cable is fixed within the main body of the nozzle.

9. A tire inflation air pressure hose nozzle apparatus, said apparatus comprising:

an air delivery nozzle having a main body and an air delivery conduit extending from main body, said main body adapted to couple to a pressurized air supply;

said nozzle including a cable having a threaded adapter attached to a first end of said cable and wherein a portion of said cable extends through at least a portion of said air delivery conduit and wherein said threaded adapter is adaptable to couple to a tire valve stem.

10. The apparatus as recited in claim 9 further including a pressure regulator coupled to said pressurized air supply.

11. The apparatus as recited in claim 9, further including a pressure feedback passageway.

12. The apparatus as recited in claim 11, further including an air return conduit coupled to said air delivery nozzle.

13. The apparatus as recited in claim 12, further including a pressure feedback sensing switch coupled in fluid communication with said air return conduit.

14. The air delivery apparatus as recited in claim 11, wherein a feedback sensor is coupled to the pressure feedback passageway.

15. The apparatus as recited in claim 9 further including a pressure feedback sensing switch coupled in fluid communication with said pressurized air supply.

16. The apparatus as recited in claim 9, wherein a portion of said cable extends out an open end of said air delivery conduit.

17. The air delivery apparatus as recited in claim 9, wherein a second end of the cable is fixed to a cable plug positioned within the main body of the nozzle.

18. A method of mounting and rapidly inflating a tire on a wheel rim, said method including the steps of:

positioning a tire on a wheel rim, wherein inner and outer tire beads of said tire are positioned between respective inner and outer flanges of said wheel rim;

positioning a valve stem within an interior of said tire adjacent an aperture formed in said wheel rim;

providing a nozzle having a main body and an air delivery conduit extending from main body, said main body adapted to couple to a pressurized air supply conduit;

providing a cable having a threaded adapter attached to a first end of said cable and wherein a portion of said cable extends through at least a portion of said air delivery conduit of said nozzle and wherein said threaded adapter is adaptable to couple to the valve stem;

extending the adapter through the aperture formed in the wheel rim and coupling the adapter to the valve stem within the interior of the tire; and

delivering a high volume of fluid from said air delivery conduit of said nozzle into the interior of the tire through the aperture formed in said wheel rim.

19. The method as recited in claim 18 further including the step of sealing said inner and outer tire beads against wheel rim.

20. The method as recited in claim 19 further including the step of applying a force to said cable to move said valve stem through said aperture formed in said wheel rim.
