摘要:
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.

A sealing and pump-up device (10) includes: a liquid agent container (18) containing a sealing agent (32); an injection unit (20) that is connected to an outlet (29) of the liquid agent container (18) and has a liquid pressurization and supply chamber (40) and a jig insertion hole (44); a jig (82) that by insertion into the jig insertion hole (44) pierces an aluminum seal (30) by means of a piercing member (62) and closes off the jig insertion hole (44); and a leading end portion (85), of an insertion portion (84), having a step (85A) that catches on an edge (44B) of a jig insertion hole (44) before the jig (82) that has been inserted into the jig insertion hole (44) reaches a piercing position, when the aluminum seal (30) is pierced.

A reliably operable sealing and pump-up device with simple jig installation and in which the jig does not come out even when subjected to pressure. The sealing and pump-up device 10 includes: a liquid agent container 18 containing a sealing agent 32; an injection unit 20 that is connected to an outlet 29 of the liquid agent container 18 and has a liquid pressurization and supply chamber 40 and a jig insertion hole 44; a jig 82 that by insertion into the jig insertion hole 44 pierces an aluminum seal 30 by means of a piercing member 62 and closes off the jig insertion hole 44; and a leading end portion 85, of an insertion portion 84, having a step 85A that catches on an edge 44B of a jig insertion hole 44 before the jig 82 that has been inserted into the jig insertion hole 44 reaches a piercing position, when the aluminum seal 30 is pierced. The jig 82 has simple installation and can be reliably operated because the jig 82 does not come out even when subjected to pressure.

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).
摘要:
When a press jig is inserted into a jig insertion hole, an O-ring attached to the outer peripheral surface of the press jig is prevented from being caught on an air supply port opening to the inner peripheral surface of the jig insertion hole and damaged. In a sealing pump-up device 10, the opening diameter of an air supply port 58 opening to the inner peripheral surface of a jig insertion hole 44 provided at one end of an air supply path 60 is set smaller than the strand diameters of an O-ring 72 and an O-ring 96. Consequently, the width at the edge of the air supply ports 58 on which the O-rings 72, 96 may possibly be caught can be made sufficiently smaller than the strand diameter of the O-rings 72, 96. When the O-rings 72, 96 pass on the inner peripheral side of the air supply ports 58 in a state of press contact with the inner peripheral surface of the jig insertion hole 44, the amount by which the O-rings 72, 96 are deformed (restored) in order to swell to the outer peripheral side so that a portion thereof fits into the air supply ports 58, can be reduced sufficiently.

Provide a sealing device with which simple and reliable operation can be performed. When stored, a liquid agent container, in which a sealing agent is contained, is temporarily held above a injection unit. When the liquid agent container is forcibly pressed downward in use, the upper end of a pressing jig penetrates through an aluminum seal into the container, and the sealing agent flows out to a compressor unit is activated and compressed air is supplied into the liquid agent container to place the pressurized sealing agent into a pneumatic tire through a joint hose.
