Abstract

Kraftstoffeinspritzventil für Brennkraftmaschinen mit einem in einem Ventilkörper (1) axial verschiebbaren Ventilglied (5), das an seinem einen Ende eine Ventildichtfläche (9) aufweist, mit der es zur Steuerung eines Einspritzquerschnittes mit einer Ventilsitzfläche (9) am Ventilkörper (1) zusammenwirkt, von der wenigstens eine Einspritzöffnung (11) in den Brennraum der zu versorgenden Brennkraftmaschine abführt und mit einem das Ventilglied (5) axial betätigenden elektrischen Stellglied (23), das über einen hydraulischen Arbeitsraum (19) auf das Ventilglied (5) wirkt. Dabei ist für eine verbesserte Steuerung der Ventilgliedhubbewegung ein zweites elektrisches Stellglied (27) zur Betätigung des Ventilgliedes (5) vorgesehen, das unabhängig vom ersten elektrischen Stellglied (23) ansteuerbar ist.
