The invention relates to a device (1) for transporting compressed air and/or sealant into a pneumatic vehicle tire, comprising at least one gas connection (3) for connecting to at least one compressed-air source (24), at least one sealant connection. (2) for connecting to at least one sealant container (6), at least two channels, wherein a first channel is a sealant transport. channel (4) for transporting a sealant dispersion from the sealant connection into a pneumatic vehicle tire and a second channel is a compressed-air transport channel (5) for transporting compressed air to the sealant connection or to the sealant transport channel, wherein the sealant dispersion comprises sealant particles and compressed air as dispersion matrix, characterized in that the device has a movable switchover element (7), wherein the movable switchover element can be moved in the direction of the sealant connection by means of a compressed-air flow coming from the gas connection and has a severing portion (8) for severing a seal. The invention also relates to a portable/transportable system (38) and to corresponding methods and corresponding uses.

Tires having a magnetic tire sealing material containing magnetic particles are described for detecting the presence of one or more sealed punctures in the tire. The tires can have a sealed tire portion that is formed by the magnetic tire sealing material flowing into and filling a puncture in the tire. The sealed tire portion includes a portion having magnetic particles and the portion being at the outer surface of the tire such as in the tread area. The tire can be positioned within the detection zone of an apparatus capable of detecting magnetic particles to indicate whether the tire contains a sealed puncture filled with the magnetic tire sealing material.

The invention relates to a device for sealing pneumatic tires by means of sealing liquid, having a sealing liquid container having an air inlet opening for connection to a compressor and an outlet opening for the discharge of an air/sealing liquid mixture into a pneumatic tire to be sealed, the sealing liquid container having at least two chambers in which components of the sealing liquid that are reactive to one another are stored separately, the chambers being separated from one another by a closed connecting element which can be opened via a pressure and/or an air flow from the air inlet opening to the outlet opening.

A plate glass repair tool has two casing members rotatably connected to one another, one of the two casing members having a screw thread defining a helical groove. The screw thread has a pitch varying in a direction from a distal end to an opposite end of the tool, an angle of inclination of the screw thread with respect to a transverse plane increasing continuously in the direction from the one end to the opposite end, a camming element extending from the other of the two casing members into the helical groove. The two casing members each comprise a cylindrical body, the cylindrical body of the other of the two casing members being disposed about the cylindrical body of the one of the two casing members.

An object of the present invention is to provide a tire sealant and a tire repair kit that exhibit excellent injectability. Provided is a tire sealant including a natural rubber latex, a synthetic resin emulsion, an anti-freezing agent, a surfactant, and a chelating agent, wherein the content of the chelating agent is 0.1 mass % or greater.

A device and method for dispensing air and/or sealant to a tire of a vehicle. Power supply for the air compressor is obtained via powered USB instead of the typical 12 V cigarette lighter connector. The position of the tire which is being inflated can also be determined via the data interface of the USB port. By communication between a compressor control module and the vehicle systems interface, the compressor can automatically switch off when the recommended tire pressure has been reached. The control module can be located in the USB power cord plug, and can provide for changes in voltage to the compressor to maximize power and inflation rate and/or efficiency.

A puncture sealing agent is disclosed which comprises natural rubber latex, an aqueous solution of an adhesive and an antifreezing agent. The adhesive is a carbohydrate and the puncture sealing agent comprises a solid content resulting from the natural rubber latex in an amount of 21 wt % or less, based on the total weight of the puncture sealing agent.

The present invention relates to a connector, a connecting assembly and a tire repairing machine. The connector comprises: a circumferential side wall defining an interior cavity of the connector; a first end wall in which a first through hole is provided, the first through hole communicating the interior cavity with an exterior of the connector; a second end wall in which a second through hole is provided, the second through hole communicating the interior cavity with the exterior of the connector, wherein, the first through hole and the second through hole are both of a non-circular shape.

The method of this invention provides a simple and inexpensive method for manufacturing self-sealing pneumatic rubber tires of the tubeless type having a higher degree of uniformity than can be made utilizing conventional manufacturing procedures that are currently being practiced. In the practice of this invention a low viscosity sealant formulation, which would ordinarily be difficult to handle and build into an uncured tire, is encapsulated in a stiff rubber formulation. This makes it relatively easy to build the sealant layer into the tire since the low viscosity sealant formulation is contained with the more rigid solid material. The low viscosity sealant material requires little and preferably no depolymerization to act effectively as a sealant. Accordingly, it does not need to be depolymerized with a peroxide which causes off-gassing and the resultant tire uniformity and balance issues normally associated with polymer break down.

A tubular structure including an outer tube an inner tube arranged within the outer tube and at least one chamber formed between the outer tube and the inner tube. The tubular structure additionally includes at least one self-healing material arranged in the chamber, wherein the self-healing material is configured to solidify and/or expand upon contact with a reacting material.
