摘要:
To reliably supply a predetermined amount of sealing agent into a pneumatic tire even if the device is inclined and after the predetermined amount of sealing agent is supplied, to automatically start feeding compressed air into the pneumatic tire. In pumping device 30, when compressed air is supplied to air chamber 54, internal pressure of air chamber 54 increases, and as the internal pressure of air chamber 54 rises, a contained volume of air chamber 54 increases while a contained volume of liquid container 52 decreases. Thus, sealing agent 100 in an amount corresponding to the amount corresponding to the reduction in the contained volume of liquid container 52, is forcibly discharged from discharge outlet 64 and the discharged sealing agent 100 is injected into tire 90. In pumping device 30, when the air chamber 54 expands enough to have a predetermined amount of sealing agent to be discharged from the liquid container 52, the air discharge opening 92 opens toward the air chamber 54 to allow the air chamber 54 to communicate with the inside of tire 90. Thus, compressed air in the air chamber 54 can be supplied into tire 90 via the air discharge outlet 92, bypass hose 96 and joint hose 68.

摘要:
A sealing/pump-up device for tire that not only ensures the storability of sealing agent but also realizes rapid supply of sealing agent into a pneumatic tire. By insertion of insert part (60A) of jig (60) in jig insertion aperture (42) of sealing device (10), aluminum seal (30) is burst through by means of boring member (50) to thereby drive the same in the container. As the distal end of the insert part (60A) locates in the vicinity of upper wall surface within liquid agent container (18), a compressor unit is operated to thereby supply compressed air into the liquid agent container (18). As the end portion of first passage (62) provided in the jig (60) lies in a position superior to the liquid surface of sealing agent (32), the compressed air realizes rapid supply of the sealing agent (32) into a pneumatic tire without surfacing in the form of bubbles through the sealing agent (32).

To prevent a burr, produced from the joint portion by welding between a liquid agent container and an injection unit, from interfering with a boring member inserted into a jig communication passage when the boring member is inserted into the jig communication passage to prevent the obstruction of the piercing action through a sealing member by the edge of the boring member. In the sealing pump-up device 10, a tubular inner annular member 104 is integrally formed on the inner peripheral side of a joined portion 37 in an injection unit 20 so as to surround, from an outer peripheral side, a boring member 62 held in a jig insertion hole 44, and a burr housing unit 106 consisting of an almost cylindrical space is formed between the outer annular member 28 of a liquid container 18 and the tubular inner annular member 104, whereby it is possible to guide the tip end side of a burr 110, extending from the joint portion between the outer annular member 28 and a joined portion 37 toward the inner peripheral side, from moving toward the boring member 62 side of the burr 110 by means of the tubular inner annular member 104.

The present invention is directed to provide a puncture-sealant that can maintain high sealing ability and is excellent in practicality. The invention is a puncture-sealant for sealing a hole in a punctured tire, the puncture-sealant including: (1) at least one type of rubber latex selected from the group consisting of SBR latex, NBR latex, carboxyl-modified SBR latex and carboxyl-modified NBR latex; (2) an antifreezing agent; and (3) at least one of a short fiber or a resin adhesive that is compatible with the rubber latex.

A production method for a supporting member without a joint, a supporting member without a joint, and a pneumatic run flat tire comprising the supporting member are obtained. The shell without a joint can be obtained by shaping a cylindrical member having a bottom part out of a metal plate by the deep drawing process, removing an opening part side and the bottom part side of the cylindrical member, and curving the cylindrical member into a shape comprising a convex part at the axial direction middle part of the cylindrical member projecting to the outside in the radial direction.
