An air maintenance tire assembly includes an air pumping passageway located within a tire sidewall to generate compressed air. An outlet screw assembly includes an elongate screw body residing within a profiled sidewall bore. The screw body extends through an axial span of the first sidewall to the tire cavity to conduct air from the sidewall air passageway to the tire cavity. The screw body has enlarged sectional end components to deter radial dislodging of the screw body from the sidewall bore during operation.

An air maintenance tire assembly having an elongate air pumping sidewall air passageway includes an inlet air passage screw assembly inserted through a tire sidewall profiled bore to conduct air from outside the tire into a regulator positioned within a tire cavity. The screw assembly includes a screw body having at an outer end a large-diameter filter housing, a smaller-diameter midsection shank portion, and an inner large-diameter valve housing connecting to the regulator within the tire cavity. A valve mechanism seats within the valve housing and moves between an open position conducting air from the screw body into the regulator assembly and a closed position preventing a backflow of air from the regulator assembly.

Devices are taught for filling a tire with air, gas or a liquid and repairing the tire. In one embodiment, the tire repair tool discloses an transmittal control section, with the transmittal control section comprising a proximal end, the proximal end having an opening a distal end, with the distal end having a centralized opening to align with a punctureable seal at a proximal end of a gas cartridge; a passageway positioned between the proximal end of the gas cartridge and the distal end; and a puncture tool which can puncture the punctureable seal of the gas cartridge. The puncture tool is positioned at the distal end of the transmittal control section along the air passage way. An insertion tube comprises an air inlet at a distal end of the insertion tube which is connected to the opening of the proximal end of the transmittal control section. A gas outlet passes air from a gas cartridge through the air passage way through the transmittal control section into the air inlet of the insertion tube and through the gas outlet.

The present invention relates to expandable bodies or systems with bounding walls or bladder structures and at least one valve assembly thermally bonded thereto. More particularly, the present invention provides a fluid valve assembly for expandable fluid-containing bodies typically made from a thermoplastic rubber material or the like, which will exhibit significantly increased strength and durability during expansion and while expanded, especially at and around the interface between the fluid valve assembly and the bounding wall of the expandable body because of the enhanced strength of the fluid valve assembly interface through thermal sealing.

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).
