Valve system for a tubeless wheel

Abstract

The invention relates to a valve system (6, 62, 64, 66) for a tubeless wheel, the wheel comprising a rim (1) and a tire (2), which form a tire/rim volume (10) that can be filled with air, and a puncture protection insert (5, 52, 54, 55, 56) positioned inside the tire/rim volume (10), the valve system comprising a valve stem body (82, 84, 86), which extends along a valve axis (A) and has a first end and a second end, and a valve base (72, 73, 74, 75, 76) adjoining said second end, the second end being positioned in the tire/rim volume (10) when the valve system (6, 62, 64, 66) is mounted on the wheel. The purpose of this is to simplify the insertion of a tube-like cannula or hollow needle of a tool for filling or extracting sealing fluid through the valve system into the tire/rim volume. According to the invention, this is achieved in that the valve base has an outer circumference that increases continuously along the valve axis (A) in the direction of the tire/rim volume, forming a thickened valve base end, and the valve system (6, 62, 64, 66) also comprises a sleeve (4, 42, 43, 44, 45, 46) having a first end and a second end, wherein the first end of the sleeve (4, 42, 43, 44, 45, 46) connects to the thickened valve base end (72, 73, 74, 75, 76) and the sleeve (4, 42, 43, 44, 45, 46) extends from there along the valve axis in a direction oriented away from the valve stem body (82, 84, 86).
