ABSTRACT:
A fuel injection device includes at least two valve elements, disposed in a housing and coaxial with one another, with at least one fuel outlet opening associated with each valve element. On the outer valve element, radially outward from the at least one fuel outlet opening associated with it, there is a first sealing edge which cooperates with a valve seat on the housing and can separate the at least one fuel outlet opening from a high-pressure connection. An additional sealing edge is provided on the outer valve element, between the at least one fuel outlet opening associated with it and the inner valve element.
