A tire valve assembly includes a valve shaft movably inserted into a first diameter section of the outer tube. The valve shaft includes a passage and a radial hole which communicates with the passage. A first seal is mounted to the end of the valve shaft that is inserted into the outer tube and is movable relative to a shoulder in the outer tube. A guide tube is mounted to the valve shaft and has a guide portion protruding therefrom which is guided in guide groove in the outer tube. An adjustment tube is threadedly mounted to the first outer threads on the valve shaft. When rotating the adjustment tube, the valve shaft is axially movable in the outer tube to control the gap between the first seal and the shoulder in the outer tube. The gap is changeable and communicates with the radial hole and the passage.

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.

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.

A tire structure disposed at a rim is provided. The tire structure includes a tire body, a flexible sealing member and a nozzle. The tire body is ring-shaped and includes a groove and two beads. The flexible sealing member is connected to the tire body to form an inflating space with the groove, and the flexible sealing member includes a through hole. The nozzle is disposed at the flexible sealing member. The nozzle includes a base and a valve stem. The base includes a screw hole and is disposed at a far side of the flexible sealing member. The screw hole corresponds to the through hole. The valve stem includes a fastening end and an inflating channel. The fastening end is configured to insert into the screw hole, and the inflating channel is configured to allow the gas to pass therethrough.

A valve stem structure disposed at a rim of a tire of a vehicle for connecting to an electronic tire pressure monitoring device in the tire is provided. The valve stem structure includes a tube, an air core, and a conducting wire. The tube has a first inlet, a first outlet communicating with an inner space of the tire, and a second outlet. The air core is switchably disposed at the first inlet, and a compressed air is injected into the tire via the first inlet and the first outlet by switching the air core. The conducting wire is disposed in the tube, and an end of the conducting wire extends out of the tube via the second outlet to be electrically connected to the electronic tire pressure monitoring device. A power source charges the electronic tire pressure monitoring device via the conducting wire.

A screw-in valve connector includes a stationary connecting pipe with a pipe body and a drive portion. The pipe body includes an air intake portion, an air discharge portion, and a receiving hole. An elastic member is disposed in the receiving hole, and includes: a press end pressed against the air intake portion, and a force-receiving end. A stop includes: a lower end inserted in the force-receiving end, a stop end, an engaging portion between the lower and stop ends to stop against the force-receiving end, and an air passage penetrating the lower and stop ends. A positioning ring is sleeved onto the stop end to abut against the engaging portion, and includes a first threaded hole for threaded connection of a French valve. A rotary ring is pivotally connected to the air discharge portion, and includes a second threaded hole for threaded connection of an American valve.
