Abstract

A fuel injector for the direct injection of fuel into the combustion chamber of a mixture-compressing internal combustion engine having external ignition includes a valve housing formed by a nozzle body, and a seal which seals the fuel injector from a cylinder head of the internal combustion engine. The seal has a sleeve-type design with a structured cross section and extends across the axial length of the nozzle body.
