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.

The invention relates to an injector for injecting fuel into the combustion chambers of an internal combustion engine, the fuel compressed in a compression unit (7) being able to be added via a pressure line (5) to a nozzle chamber (4) surrounding a nozzle needle (3) of the injector (1) is. This is connected to the injection nozzle (6) projecting into the combustion chamber of an internal combustion engine, a fluid control unit being contained in the injector. The fluid control unit is designed as a hydraulic module that is replaceably arranged in the housing (2) of the injector (1). (14, 31, 36, 42), which can be actuated either by actuators or electromagnets.
