A fuel injector has a solenoid which cooperates with an armature acted upon by a restoring spring, the armature, together with a valve needle, forming an axially movable valve part. A valve closing body which forms a seat seal with a valve seat body is provided on the valve needle, the seat being form-fitted in a seat support which forms the downstream interface to the inlet pipe or the combustion chamber and is made of plastic. The connection fitting, which forms the upstream interface to the central fuel supply, is preferably also manufactured from plastic.
