Abstract

A portable device for delivering nitrogen to multiple tires includes a gas source and supply line connected to a controller. The device also includes a gas delivery line comprising a manifold with a plurality of outlets in fluid communication with each other. A gas delivery line is operably connected to the controller and a plurality of extension lines with engagement chucks are operably connected to the outlets. The controller controls the supply of gas to the gas delivery line and controls a relief valve for venting the gas delivery line. The device also includes a sensor and a processor connected the controller and sensor which accepts user inputs. The controller, manifold and processor are affixed to a stand.

Claims

1-16. -16. (canceled)

17. A method of ensuring pressure equalization between a plurality of tires during evacuation and inflation of the tires, comprising:

providing a plurality of supply hoses in fluid communication with each other;

attaching each of the supply hoses to a corresponding valve stem on the plurality of tires;

supplying pressurized gas from a gas source to said plurality of tires via the supply hoses;

monitoring and controlling a gas characteristic of the pressurized gas in the plurality of supply hoses to thereby inflate the plurality of tires to a predetermined pressure to thereby ensure pressure equalization between each of the plurality of tires.

18. The method of claim 17 further comprising:

inputting into a processor the number and identity of the plurality of tires

retrieving tire data associated with the identity of the plurality of tires

determining the predetermined pressure based on tire data and at least one monitored gas characteristic.

19. The method of claim 17 wherein the pressurized gas is nitrogen.

20. The method of claim 17 wherein the gas characteristic is selected from the group comprising:

pressure, temperature, concentration and flow rate.
