ABSTRACT:
A fuel injector for the direct injection of fuel, especially into the combustion chamber of a mixture-compressing internal combustion engine having external ignition, is located in a cylinder head of the internal combustion engine in a receiving bore of the cylinder head, and includes a nozzle body and a sealing ring which seals the fuel injector from the cylinder head of the internal combustion engine. At an end on the discharge side of the fuel injector, an at least partially spherical body is formed which abuts at least partially against a wall of the receiving bore, a groove being circumferentially formed on the body in which the sealing ring is positioned.
