Abstract

Die Erfindung betrifft eine Kraftstoffeinspritzventileinrichtung mit einem Ventilkolben (55), der ein Ventilkolbenende (54) aufweist, das in einem Ventilstück (44) einen Ventilsteuerraum (58) begrenzt, der über eine Ablaufdrossel (81) mit einem Druckentlastungsraum (68) verbindbar ist.The invention relates to a fuel injection valve device having a valve piston (55) which has a valve piston end (54) which delimits a valve control chamber (58) in a valve piece (44) which can be connected to a pressure relief chamber (68) via an outlet throttle (81).

Um eine Kraftstoffeinspritzventileinrichtung zu schaffen, die kostengünstig herstellbar ist und ein gutes Einspritzverhalten aufweist, ist die Ablaufdrossel (81) in einem Ablaufdrosselstück (80) vorgesehen, das in das Ventilstück (44) eingelegt ist.

Figure imgaf001
In order to provide a fuel injection valve device which is inexpensive to produce and has a good injection behavior, the outlet throttle (81) is provided in a discharge throttle (80) which is inserted into the valve piece (44).
