Abstract
This is an apparatus and system for integration of Central Tire Inflation (CTI) valve functionality directly into a wheel. The CTI valve may be attached to the wheel or integrated into the wheel. In addition, the CTI valve may have a valve body or the valve components can be installed directly into the wheel. An air passageway between the vehicle air source and the CTI valve and/or an air passageway from the CTI valve to the tire cavity can also be employed.
Claims8
An apparatus and system for integration of a CTI valve into a wheel, comprising:
- a wheel including a circular wheel rim having formed coaxially on opposite ends thereof outwardly flaring circumferential flange sections disposed to be engaged by the beads of a tubeless tire mounted on the rim, said wheel rim having intermediate said opposite ends thereof a transverse wall section extending transversely of the axis of said rim, and having therethrough a central opening disposed coaxially of said axis;
- a CTI valve including a valve body enclosing internal parts, which valve body is at least partially embedded within said wheel, which CTI valve receives air from an external source and communicates said air to the interior of the tire mounted thereon through an air passageway in said wheel;
- and
- wherein said air passageway in said wheel in communication with said CTI valve and the interior of the tire is open on one side so as to form a groove in said wall section, and further comprising a sealing plate covering said groove and sealing said one side of the passageway.

- a CTI valve including a valve body enclosing internal parts, which CTI valve can receive air from an external source and communicate said air to the interior of the tire mounted thereon;
- wherein said wheel is a multi-piece wheel comprised of two pieces that can be bolted together with an o-ring coaxially disposed between said two pieces;
- and
- wherein said CTI valve is in a recess formed intermediate said two pieces such that the CTI valve is completely enclosed when the said pieces are bolted together.
