A tire repair kit is described for inflating and/or sealing a tire mounted on a rim of a vehicle wheel. The tire repair kit may include a support body configured to be replaceably received in a central recess of the vehicle wheel rim, and a compressor unit including a drive and a compressor portion having at least one working chamber. The drive may be received inside of the support body, and the compressor portion may be releasably connected to a flange region of the support body and is outside of the supporting body. With the supporting body received in the central recess of the vehicle wheel, the drive of the compressor unit is arranged at least in certain regions of the central recess and the compressor portion of the compressor unit is completely outside the central recess.

A tire sealant dispenser matches with an air compressor and contains a body in which chemical fluid (such as tire sealant) is filled, a cap connected on an opening of the body, a drive element configured to urge a punch element to pierce a film, such that an air conduit is in communication with a sealant conduit, pressurized air flows into the body via the air conduit from the air compressor, and the chemical fluid flows out of the sealant conduit.

A tire repair apparatus is described for dispensing sealant formulation which is substantially formed of PET and provided with an integrally formed neck or base inlet which itself is additionally provided with a valve or plug within an internal channel thereof. The apparatus is a more environmentally-friendly dispenser and provides for advantages during dispensing of sealant.

The invention relates to a self-sealing pneumatic vehicle tire having a belt package (2), a tread (1) arranged radially above the belt package (2) and an airtight inner layer (4) arranged radially on the inside, wherein the self-sealing of the pneumatic vehicle tire is obtained via a sealant layer (5) subsequently applied radially on the inside after the vulcanization of the pneumatic vehicle tire, wherein the sealant layer (5) has essentially the width of the belt package (2) and is arranged essentially in the projection thereof and has a cross section which is formed in a cross-sectional plane including the tire axis and has a surface (5a) running essentially parallel to the belt package in axial direction and a surface (5b) running essentially in radial direction.

It is a feature of the invention that at least the surface of the sealant layer (5a) running essentially parallel to the belt package in axial direction has a circumferential coating (6) that contains at least elastomer particles.

In the method of the invention, the sealant layer is coated at least with elastomer particles.

An aerosol product diffuser assembly comprises: a diffuser block (1) comprising an annular casing (2) inside which a cam actuator (3) is mounted axially mobile, a control lever (10) provided with a planar body (12) making it possible to control the diffusion of the aerosol liquid said cam actuator (3) comprising: (i) an axially mobile cam follower plate (4); (ii) an aerosol bottle nozzle housing (5), arranged on the cam follower plate (4); (iii) a duct (6a) connected to the nozzle housing and enabling the liquid to diffuse to a discharge point of the aerosol liquid, the control lever (10) being pivotably mounted on the annular casing (2), and the cam actuator (3) being able to be pushed axially towards the aerosol bottle by at least one pivoting cam (15).

A tire repair machine has a base with a tire support, a clamp, and an injector. The clamp is releasably holds a tire for repair on the tire support. The injector is movable relative to the base and forces melted compound into a repair zone of the tire for repair. There is also provided a method of repairing a tire that utilizes a tire repair machine. A tire is clamped in the tire support of the base. The repair zone is drilled to clear the area to be repaired. A melted compound is injected into the repair zone of the tire. Once repaired, the tire is released from the clamp and tire support of the base.

By the present invention, an inner lid is easily removed by upward thrusting of a sheath tube while detachment of the inner lid during storage is suppressed. An extraction cap is provided with: a cap body provided with a barrel part, a top-end part of which attaches to a mouth of a bottle container, and an air supply tube standing from a bottom portion of the barrel part and forming a first flow channel; and a sheath tube arranged and retained around an exterior of the air supply tube so as to be able to slide up and down. An inner lid is fitted on a top-end part of the air supply tube. An annular first retaining protrusion extending in the circumferential direction is formed on an external peripheral surface of the air supply tube, and a second retaining protrusion retained by the first retaining protrusion and comprising a plurality of retaining protrusions arranged at intervals in the circumferential direction is formed on an internal peripheral surface of the inner lid.

A flat tire repair liquid container is provided with: a closing stopper, which is formed from a non-elastomer material and is capable of sliding inside a flow channel; and a sealing member, which is formed from an elastomer material, is disposed in a ring shape conforming to an inner wall surface of a flow channel, closes a gap between the closing stopper and the flow channel, and holds the closing stopper at a predetermined position. During storage, the closing stopper is engaged with the sealing member to close the flow channel. During flat tire repair work, the closing stopper is pushed out from the sealing member by pressure inside the container and moved toward the outer side of the container in the flow channel to open the flow channel.

The present disclosure provides tire repair assemblies, methods for repairing tires, standalone currency operated tire repair assemblies, tire sealant vending assemblies configured to provide tire sealant via the valve stem of a tire, tire valve coupling assemblies that are configured to provide gas and/or sealant to a tire, tire valve coupling assemblies, and/or methods for providing one or both of gas and/or tire sealant to a tire are provided.

There is provided a crack repairing method for suppressing a crack growth in a wall portion. The crack repairing method includes an injection step in which working fluid is injected into a crack formed into a surface of the wall portion of a target object and a vibration step in which vibration is applied to the working fluid in a direction from an crack initiation portion of the crack on the surface to an inner end portion of the crack. The crack repairing method further includes a deformation step in which a cavity is generated in the working fluid by the applied vibration and compressive residual stress is generated at the inner end portion of the crack.
