Automotive wheel with improved inflation system
DCFirst Claim
1. An automotive wheel for use with a tubeless tire, comprisinga circular 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 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 first air duct formed within said wall section to open at one end thereof on the outer periphery of said rim for communication with the interior of the tire mounted thereon, and opening at the opposite end thereof on one side of said wall section, a second air duct formed within said wall section to open at one end on said one side of said wall section and opening at its opposite end on the opposite side of said wall section for connection to a tire inflation system, and a tire inflation control valve secured to said one side of said wall section and having therein a pair of air inlet/outlet ducts, one of said pair of ducts being sealingly secured at one end thereof to said opposite end of said first duct, and the other of said pair of ducts being sealingly secured at one end thereof to said one end of said second duct.

Abstract
An automotive wheel rim has intermediate its ends a wall extending transversely of the axis of said rim and having formed therein a first air duct opening at one end on the outer periphery of the rim for communication with the interior of a tire mounted thereon, and at its opposite end on the outboard side of the wall. A second duct formed within the wall opens at one end on the outboard side of the wall and at its opposite end on the inboard side of the wall for connection to a tire inflation system. A tire inflation control valve is secured to the outboard side of the wall and has therein a pair of air inlet/outlet ducts sealingly secured in communication with the ends of the first and second ducts where they open on the outboard side of the wall.
