Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zum Einspritzen von Kraftstoff mit einem Injektor (1) der einen Druckraum (13) enthält. Vom Druckraum (13) aus erstreckt sich eine Hochdruckleitung (5) durch das Injektorgehäuse (2), in welchem eine mittels einer Düsennadel (4) verschließbaren Düse (3) angeordnet ist, wobei die Düsennadel (4) mittels eines Kraftspeichers (7) beaufschlagt ist. Es sind über ein Aktorelement (11) unabhängig voneinander einstellbare und ansteuerbare Steuerventile (8, 10) vorgesehen, die über einen Kopplungsraum (9) miteinander in Verbindung stehen und über die der Einspritzdruckverlauf (24) steuerbar ist.
