Abstract (en)
[origin: WO2017092955A1] The invention relates to a fuel injector (100) for injecting fuel into the combustion chamber of an internal combustion engine. The fuel injector (100) comprises a control valve (1) and an injection valve element (11). The injection valve element (11) bounds a control chamber (15) and is guided in the fuel injector (11) in such a way that the injection valve element can be moved longitudinally. The injection valve element (11) opens and blocks at least one injection opening (13) into the combustion chamber by means of the motion of the injection valve element. The control valve (1) controls the pressure in the control chamber (15). The control valve (1) comprises a magnet assembly (2), an armature (5), a valve piece (4), and a valve seat (7) formed on the valve piece (4). The armature (5) comprises an armature plate (50), which can be controlled by the magnet assembly (2). The armature (5) interacts at least indirectly with the valve seat (7) in order to relieve the control chamber (15). A crown ring (20) is clamped between the valve piece (4) and the magnet assembly (2).
