Abstract
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, when compressed air is supplied to air chamber, internal pressure of air chamberincreases, and as the internal pressure of air chamberrises, a contained volume of air chamberincreases while a contained volume of liquid containerdecreases. Thus, sealing agentin an amount corresponding to the amount corresponding to the reduction in the contained volume of liquid container, is forcibly discharged from discharge outletand the discharged sealing agentis injected into tire. In pumping device, when the air chamberexpands enough to have a predetermined amount of sealing agent to be discharged from the liquid container, the air discharge openingopens toward the air chamberto allow the air chamberto communicate with the inside of tire. Thus, compressed air in the air chambercan be supplied into tirevia the air discharge outlet, bypass hoseand joint hose
