Abstract

Die Erfindung bezieht sich auf einen Injektor zum Einspritzen von Kraftstoff in die Brennräume einer Verbrennungskraftmaschine, wobei der in einer Verdichtungseinheit (7) komprimierte Kraftstoff über eine Druckleitung (5) einem eine Düsennadel (3) des Injektors (1) umgebenden Düsenraum (4) zufügbar ist. Dieser steht mit der in den Brennraum einer Verbrennungskraftmaschine hineinragenden Einspritzdüse (6) in Verbindung, wobei im Injektor eine Fluidsteuerungseinheit enthalten ist. Die Fluidsteuerungseinheit ist als im Gehäuse (2) des Injektors (1) auswechselbar angeordnetes Hydraulikmodul. (14, 31, 36, 42) beschaffen, welches entweder aktor- oder elektromagnetisch betätigbar sein kann.
