Abstract
A fuel injection valve includes at least two throttling constrictions. The fuel is guided in so that it flows through one of the throttling constrictions with a flow component directed away from the spray orifice. Thus, at least partially compensating opposing force is exerted on the valve needle or an element (e.g., an armature) with a non-positive connection to the valve needle.
