<p>The subject of the invention is an apparatus for repairing the punctures in tubeless tyres by means of rubber rivets and without detaching the tyre from the motor vehicle rim. It comprises a pneumatic power cylinder with a displaceably mounted piston and a separable pull-through. At its free end, the tubular pull-through is provided with a conical butting face, which gradually merges with the conical end of a removable mandrel, provided in the hollow space of the pull-through. At its remote end, the mandrel has a circumferential fixing face, the outer diameter of which is greater than the diameter of a hollow space for guiding the piston rod of the piston. Between the piston and the end face of the piston working chamber, facing this hollow space, a flexible element is provided. An opening in the power cylinder serves for connecting a compressed-air source.</p> |
