Apparatus for the sealing and pumping up of tyres

摘要

A sealing preparation for tyre 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 tyre. 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 tyre and for the pumping up. An air compressor, or liquefied dinitrogenoxide, or sulphur hexafluoride are preferably used with these devices as a pressure source.
