Abstract:
A fuel injection device for an internal combustion engine includes a housing and a valve element which is arranged in the housing. The valve element interacts, in the region of a fuel outlet opening, with a valve seat. The valve element is embodied by at least one first part and at least one second part which are coupled to one another by means of a hydraulic coupler. The hydraulic coupler has a coupling chamber which is delimited at least partially by a sleeve which is guided on the first part of the valve element. Additionally a guide element guides an end region of the first part of the valve element, which end region being oriented toward the second part of the valve element.
