Abstract:
Device for repairing a tire fault by injecting a repair liquid into the faulty tire, said liquid being present in a compressible liquid storage volume, characterized in that (i) the liquid storage volume includes a watertight first sealing point to be opened and is located in a pressurized container subject to the pressure of a pressurized gas from a pressurized gas source in a compression chamber which becomes larger as it is affected by the pressurized gas, (ii) the first sealing point is disposed between the liquid-containing volume and a flexible delivery tube and is opened in response to the pressure of the pressurized gas source such that the volume delivers repair liquid to the tire through the opened first sealing point via the flexible delivery tube until no more liquid can be extracted, and (iii) the pressure in a chamber arranged above or in the pressurized container subsequently is dropping, and the pressure difference between the pressurized gas delivery channel and the chamber is rising, such that a second sealing point located between the delivery channel and the chamber is opened and clears a channel from the pressurized gas source via the flexible delivery tube to the tire.
