Abstract
A thermal insulating sleeve for a fuel injection valve, which can be inserted in a mounting hole of a cylinder head of an internal combustion engine, has a sleeve body which at least partially envelops a nozzle body of the fuel injection valve. At the injection end of the sleeve body there is a folded-back section, in which the sleeve body has a two-layered configuration, and there is a conical section, which tapers in the direction toward the injection end and which in the assembled state fits tightly against the tapered section of the nozzle body.
