A valve stem support apparatus for supporting a valve stem while attached to a pump includes a bracket having a bracket top side, a bracket right side and a bracket left side. The bracket top side has a valve aperture extending therethrough. The valve aperture slidingly receives a valve stem of a tire of a bicycle. Each of the bracket left side and the bracket right side has a screw aperture extending therethrough. A receiving distance between the bracket right side and the bracket left side is wider than a rim of the bicycle. A pair of thumb screws is coupled to the bracket. The pair of thumb screws is threadingly engaged with the screw apertures of the bracket left side and the bracket right side to engage the rim of the bicycle and secure the bracket.

A tire parameter monitoring system has an electronic module with a fitting for a snap-in valve, an adapter with first lamellae couplable to the fitting, a valve stem for a clamp-in valve with second lamellae that are interleavable with the first lamellae, and a pin. The first lamellae have a first hole extending substantially perpendicularly to a major surface of the first lamellae and the second lamellae have a second hole extending substantially perpendicularly to a major surface of the second lamellae. The first and second holes are aligned when the first and second lamellae are interleaved. The pin is inserted into the first and second holes to secure the adapter and the valve stem together and to allow rotational movement of the adapter and the valve stem around a longitudinal axis of the pin such that the valve stem is positionable at different angles to the electronic module.

A TPMS inflation valve for a commercial vehicle includes an inflation valve body, an inflation valve seat and a sensor subassembly. The inflation valve body and the inflation valve seat are components split apart from each other. The inflation valve is mounted on an automobile rim by means of the inflation valve seat, and the inflation valve body is provided with an installation portion for a valve core. The inflation valve body and the inflation valve seat are assembled and connected to form an airflow channel for communication. A cavity located outside the automobile rim and close to the automobile rim is formed at the position where the inflation valve body and the inflation valve seat are assembled and connected. The sensor subassembly is arranged in the cavity in communication with the airflow channel of the inflation valve or located on the airflow channel.

A valve stem having a hollow tube and a compression sleeve mounted to the hollow tube; wherein the hollow tube and compression sleeve are partially insertable through a container wall opening from an exterior side of the container wall through to an interior side of the container wall, and a mechanism accessible from the exterior side of the container wall to compress the compression sleeve against the interior side of the container wall.

Provided is a tire information acquisition device. A sensor unit substrate on which a sensor for acquiring tire information and a power supply unit for supplying electric power to the sensor are disposed is provided, and a heat-insulating material is disposed at at least a periphery of the power supply unit.

The present invention relates to a device for mounting tubeless tire comprising an elongated balloon having an opening attached to a bicycle tire valve. The balloon is fabricated from latex or any other suitable elastic material, and is filled with a tire sealant composition. Further, the ballon is designed to burst at a pressure of 15-40 psi.
