Estimating the term…
A sealing preparation for tire problems is proposed which seals in wet conditions, at low and high temperatures and with defects at the transition between the tread and the side wall of the tire. The sealing preparation contains natural rubber latex or a combination of rubber latex and compatible adhesive resin. Furthermore, various devices are proposed for introducing the sealing preparation into the tire and for the pumping up. An air compressor, or liquefied dinitrogenoxide, or sulphur hexafluoride are preferably used with these devices as a pressure source.
An apparatus for the sealing of punctures in and pumping up of a tire comprising:
An apparatus for sealing punctures in and pumping up a tire comprising:
An apparatus for sealing punctures and pumping up a tire comprising:
An apparatus for the sealing of punctures and pumping up of tires, comprising a pressure-tight container containing a sealing preparation, the container having an outlet valve for the sealing preparation, a source of pressure for introducing the sealing preparation from the pressure-tight container into the interior of the tire and for the reinflation of the tire, said apparatus also comprising a source of heat for heating up the sealing preparation in the pressure-tight container and/or for the heating up of the pressure source and wherein the pressure-tight container contains a sealing preparation comprising a natural rubber latex, an adhesive resin compatible with the rubber latex, and a freezing protection agent, the solid content of said sealing preparation being in the range of 45% to 55% by weight of the total preparation and the weight ratio of rubber latex to adhesive resin being 4:1 to 1:1.
