An air chuck includes a body and a valve core interface. The body includes output, interface, and input ports. The body defines a first passageway that extends between the output and interface ports. The input port defines a second passageway that is in fluid communication with the first passageway. The valve core interface is slidably coupled with the body and is slidable between extended and retracted positions. The valve core interface includes a shaft and a knob. The shaft includes proximal and distal ends. The distal end is at least partially disposed in the first passageway. The knob is coupled with the proximal end of the shaft. The shaft is rotatably coupled with the body and is selectively rotatable in either tightening or loosening directions via the knob. The distal end of the shaft comprises a grasping feature that is configured to grasp a valve core of a valve stem.

An inflation valve for a tubeless tire may include a valve body defining a cavity having a proximal opening and a distal opening. A valve stem extends through the cavity and includes a plug at a proximal end of the valve stem. The proximal opening of the cavity is defined by a beveled surface, and an outer diameter of the beveled surface is larger than an inner diameter of the valve body. The valve is transitionable between: a) a closed position, where a resilient surface of the plug engages the beveled surface to seal the cavity, and b) an open position, where the resilient surface of the plug is spaced from the beveled surface to unseal the cavity.

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.

A combination structure for a hose connected between a tire and an air compressor is disclosed. The air compressor includes a box in which a compressor unit and a sealant bottle are installed. The sealant bottle has an inlet and an outlet. The inlet of the sealant bottle is connected to one outlet tube of the compressor unit. The hose has a first end and a second end. The first end of the hose is adapted to be connected to the outlet tube of the sealant bottle. The second end of the hose can be connected to the combination structure, which generally includes a cap, a core element, and a plug. With the combination structure, the chemical sealant contained in the sealant bottle can be prevented from flowing out to contaminate objects due to incorrect operation or negligence.

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.

An air chuck includes a body and a valve core interface. The body includes output, interface, and input ports. The body defines a first passageway that extends between the output and interface ports. The input port defines a second passageway that is in fluid communication with the first passageway. The valve core interface is slidably coupled with the body and is slidable between extended and retracted positions. The valve core interface includes a shaft and a knob. The shaft includes proximal and distal ends. The distal end is at least partially disposed in the first passageway. The knob is coupled with the proximal end of the shaft. The shaft is rotatably coupled with the body and is selectively rotatable in either tightening or loosening directions via the knob. The distal end of the shaft comprises a grasping feature that is configured to grasp a valve core of a valve stem.

A self-healing pneumatic tire, which uses the sealant stored in the tire to fix a leak, is disclosed.

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.

The purpose of the present invention is to prevent an extraction cap from getting detached under high-temperature environments while minimizing the force for attaching the extraction cap under low-temperature environments. A connecting means (7) for connecting a compressor (3) and an extraction cap (5) is composed of first and second connecting portions (7A, 7B). The first connecting portion (7A) has a hook pawl portions (28) at the tip end part of each of a pair of plate-shaped base portions (27) extending in a coupling direction from the extraction cap (5) through on both sides of an intake port portion (10), the hook pawl portions (28) having a triangular cross-sectional shape and including a locking surface (28S) projecting outwardly. The second connecting portion (7B) has an engaging surface (29S) that engages with the locking surfaces (28S). The angle 1 of the locking surfaces (28S) is different from the angle 2 of the engaging surfaces (29S); or a plate-shaped portion (40) which is a region from the rear end in the coupling direction, of the plate-shaped base portion (27) to the hook pawl portion (28), has a constant width portion (40A) and a constricted portion (40B).

An apparatus including a pouch and a valve stem. The pouch can include a sealant. The valve stem can be fluidly coupled to the pouch.
