ABSTRACT:
A fuel injector, e.g., for fuel injection systems of internal combustion engines, for direct injection of fuel into the combustion chamber of an internal combustion engine. The fuel injector includes a solenoid, an armature, which is acted upon in a closing direction by a restoring spring, and a valve needle, which is linked in a force-locking manner to the armature, for actuating of a valve-closure member, which together with a valve-seat surface forms a sealing seat. The armature includes a first armature part and a second armature part, the restoring spring is supported on the first armature part and the second armature part is linked in a force-locked manner to the valve needle. The valve needle is acted upon in the closing direction by the restoring spring via the first armature part and the second armature part so that the valve-closure member is held in a sealing position on the valve-seat surface.
