Abstract

Es wird ein Einspritzventil vorgeschlagen, mit einem ventilartig ausgebildeten Ventilsteuermodul (11), das ein in einem Ventilraum (20) angeordnetes Ventilschließglied (17) umfasst, das mit zwei Ventilsitzen (18, 19) zusammenwirkt und in eine Mittelstellung verfahrbar ist, sowie mit einem Düsenmodul (12), das einen Ventilsteuerkolben (33) aufweist, der an einen mit dem Ventilraum (20) des Ventilsteuermoduls (11) verbundenen Steuerraum (28) grenzt und mit einer Düsennadel (38) zusammenwirkt, die in Schließstellung mindestens eine Einspritzöffnung (41) sperrt. Erfindungsgemäß ist zwischen dem Ventilsteuerkolben (33) und der Düsennadel (38) ein Düsensteuerraum (27) ausgebildet, der über einen Kanal (23) mit dem Ventilraum (20) des Ventilsteuermoduls (11) verbunden ist, so dass ein Fluiddruck in dem Düsensteuerraum (9) regelbar ist (Figur).
