An anti-jet joint structure of a connection hose of a vehicle air compressor contains: an accommodation box, an adhesive supply can, and a connection hose. The accommodation box accommodates the vehicle air compressor started by a power to produce air. The adhesive supply can accommodates chemical adhesive for repairing a tire, and the adhesive supply can includes an open segment and a supply hose. The connection hose includes a first joint and a second joint opposite to the first joint. The first joint is engaged with the supply hose, and the second joint is screwed with a gas nozzle of the tire. The second joint is the anti-jet joint structure and has a first connection assembly and a second assembly. The first connection assembly is connected with or is removed from the second connection assembly having different interior structures and volumes so as to mate with various tires.

An inflation system for tubeless bicycle tires may include a valve, a sealant canister, a pump head, and/or a valve core adapter. The valve, sealant canister, and pump head may collectively facilitate sealant injection into a tire by a user. The valve has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and a retaining mechanism for the valve stem disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body.

A check structure for a connection of an air nozzle of a tire and a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has a check connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a hollow room, a stepped coupling segment, a conduit, and a tilted fence. A valve bolt includes a post, a connecting disc, multiple peripheral channels, a neck, multiple spaced slots, and a seal ring. A first spring is received into the conduit from the stepped coupling segment of the cylindrical base.

An air compressor contains: a box in which the air compressor and a sealant supply device are accommodated. The air compressor is configured to produce high-pressure airs, and the sealant supply device has an air inlet pipe and a supply pipe. An air outlet pipe of the air compressor is connected with the air inlet pipe, and the air compressor is detachable from the sealant supply device. The air inlet pipe is configured to receive the high-pressure airs from the air compressor, the supply pipe is configured to output chemical sealant from the sealant supply device, and a tube is configured to communicate the air inlet pipe with the supply pipe. A rotation element includes a driven portion and a central stem. The rotation element is fitted on the second sub-tube. The central stem of the rotation element abuts against a top of the tube.

A check joint structure for a connection of an air nozzle of a tire and a connector of a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has a check connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room to abut against the first stepped portion. A valve bolt includes a contacting element fitted thereon.

The present application relates to a tire repairing system, comprising: an inflation device including an inflation housing and a motor; and a sealant container having a container housing, an air outlet of the inflation device can be connected to an air inlet of the sealant container, wherein the inflation housing is able to connect to the container housing in such a way that the container housing acts as a pedestal and the inflation housing is arranged on the container housing.

The invention is directed to a valve stem system (1) for tubeless wheels. The valve stem system (1) includes a valve stem body (2) with a first end (3) and a second end (4), wherein the second end (4) is located in a tire/rim-volume when mounted at the wheel. A first valve (5) is arranged at the second end (4) of the valve stem body (2). The first valve (5) is a self-sealing one-way valve. A second valve (10) is removably mountable at the first end (3) and is, when mounted, at least partially housed in the valve stem body (2). The second valve (10) comprises a valve stem core inserted in the valve stem body (2) and can be added or removed from the valve stem body (2) while pressure is maintained within the tire by the first valve (5). The invention further concerns a probe (30) for a valve stem system, a method to test the amount of sealant in a wheel and a refilling assembly (80) for a wheel.

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.

The present invention provides a tire valve stem assembly for a pneumatic tire having a valve stem for inflating the tire and having a member extending from the valve stem into an interior of the tire to prevent clogging or minimize clogging of the valve stem by leak sealing material.
