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.

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.

To be able to simply carry out an operation of repairing a punctured pneumatic tire, to be able to inject a necessary amount of a sealing agent firmly into the pneumatic tire even when the apparatus is used in an inclined state and to prevent clogging of the sealing agent and leakage of a liquid by being pressurized.A pump up apparatus 30 is an apparatus for injecting a sealing agent in a liquid state into a punctured pneumatic tire 38, thereafter, supplying compressed air into the pneumatic tire 38 to elevate an inner pressure thereof. The pump up apparatus 30 includes a sealing agent vessel 34 accommodating the sealing agent, a sealing agent injecting pump 42 for sucking the sealing agent from the sealing agent vessel 34 to feed it to the pneumatic tire 38, and a compressor 44 for pressurizing and sending air to the pneumatic tire 38. When the pneumatic tire 38 is punctured, the sealing agent injecting pump 42 sucks the sealing agent in the liquid state from the sealing agent vessel 34 to inject it to the pneumatic tire 38, therefore, inside of the sealing agent vessel 34 is not pressurized.

摘要:
A sealing agent stock solution 20 is prepared by preparing a mixed solution 14 by mixing a rubber latex, a resin emulsion and a surfactant, and a predetermined amount of water in a solution preparation vessel 12, followed by adding an anti-freeze agent 18 to the mixed solution 14. The sealing agent stock solution 20 is held (left standing still) at least over for 24 hr or more and preferably over for 48 hr or more without stirring in the solution preparation vessel 12, followed by filtering the sealing agent stock solution 20 with a filter member 26 made of a mesh filter having the mesh number from 50 to 400 mesh to remove latex aggregates 36 generated in the sealing agent stock solution 20, and thereby a sealing agent 10 that does not contain the latex aggregates 36 is produced.
