Abstract

Die Erfindung betrifft eine Steuerventileinrichtung für einen Kraftstoffinjektor, mit einer Ventilnadel (20), die zum Ausführen eines Ventilnadelhubs hin und her bewegbar geführt ist, der durch ein Hubanschlagelement (40;50) begrenzt ist, das wiederum einen Quetschspalt (45;55) begrenzt.
Um das Schaltverhalten zu verbessern, ist das Hubanschlagelement relativ zu der Ventilnadel und/oder die Ventilnadel (20) relativ zu dem Hubanschlagelement (40;50) begrenzt verlagerbar.
