An outlet coupling for a sealant container comprises a connector having an open first end to engage with a tire valve stem and an open second end continuous with a channel. The outlet coupling also comprises a pin at least partially located within the channel, the pin comprising a body having a head and an engaging portion at substantially opposite ends thereof. The head is in contact with a biasing member and the engaging portion is engaged with a sealing element. The pin is movable between an open position wherein the sealing element is spaced from an end of the channel and a closed position wherein the sealing element seals the end of the channel. Methods of sealing a puncture in an inflatable article, such as a pneumatic tire, with a tire repair apparatus using the outlet coupling are also disclosed.

An embodiment of the present invention provides an air injection valve-integrated spray for spraying and applying polyurethane foam to a desired portion of a tire. The spray includes a polyurethane foam chamber disposed at an end of a coupling portion and keeping polyurethane foam under pressure and an air delivery chamber delivering air injected from an air injection valve to a breaking portion of the polyurethane foam chamber, in which the breaking portion of the polyurethane foam chamber is broken by air coming out of the air delivery chamber, so the polyurethane foam is sprayed.

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 fuel solution introducing method introduces a fuel solution into a tire. The tire includes a transmitter configured to transmit data that includes a detection result detected by a sensor to a receiver. The transmitter is operated with, as a power source, an organic power generation element configured to generate power through a chemical reaction with organic matter contained in the fuel solution. The fuel solution introducing method includes introducing the fuel solution and gas into the tire from a tire valve arranged on a wheel to which the tire is attached.

An apparatus for dispensing pressurized air and/or tire sealant from a pressurized can. The apparatus comprising a nozzle and a locking element for the nozzle and/or a cap including a free length of hose that is positioned within the cap. The locking element locks the nozzle in the non-dispensing position for safety during non-use or in a dispensing position for ease of use. The hose provides an extension for the nozzle for hard to reach places, and stores fully wound within the cap, such as along the inner circumference of the cap.

A vehicle includes: a sensor for measuring a relative position and a relative speed between an obstacle and the vehicle; an injector for injecting a deforming material which is solidified during injection to absorb an impact and enhance coupling strength at a portion to which the deforming material is attached; and a controller configured to determine a collision probability with the obstacle based on the measured relative position and the measured relative speed, to determine a predicted collision position when the collision probability reaches a reference collision probability, to determine an injection direction of the injector based on the predicted collision position, and to control the injector to inject the deforming material in the determined injection direction.

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 vehicle with a compressor assembly for supplying pressure medium to a tire cavity of a tire of the vehicle wheel mounted on a wheel hub, wherein the wheel hub is mounted on a wheel carrier so as to be rotatable about an axis of rotation. The compressor assembly is located at or in the wheel hub mount.

A tubeless air valve stem has a body, an airtight element, and a sleeve. The body has a passage, a through hole, and at least one side hole. The passage is formed on a top end of the body. The through hole is formed through a bottom end of the body and is in communication with the passage. The at least one side hole is formed through an outer surface of the body and is in communication with the passage. The airtight element is disposed around the body. The sleeve is disposed around the body for closing the at least one side hole. Gas or liquid can be injected into a tubeless tire via the at least one side hole. The intake efficiency of the tubeless air valve stem can be maintained and is not influenced by the remaining reinforcing agent.

Provided is a puncture repair liquid holding container. An outflow channel in a cap mounted to an opening portion of a container body for discharging the puncture repair liquid inside the container interior to a container exterior includes a straight portion including an open end opening toward inside the container body and a closed end terminating inside the cap, and a branching portion including a communicating end communicating with an intermediate area of the straight portion and an open end opening toward the container exterior. A through-hole is at the closed end of the straight portion. A projection on a closing plug and slidably inserted to the straight portion is slidably inserted to the through-hole. States are switchable between open and closed states in which the outflow channel is opened and closed by the closing plug and the projection is positioned in the through-hole or projects from the through-hole.
