Abstract
A fluid metering valve includes a valve needle that is actuatable by an electromagnetic actuator that includes an armature guided on and along a longitudinal axis of the valve needle with a movement limited by a stop surface on the valve needle. A projection of an edge of the stop surface extends into a projection plane, perpendicular to the longitudinal axis and at which the armature and stop surface are in contact temporarily during operation, through an opening of a conduit of the armature, dividing the opening into an inner surface on one side of the projection and an outer surface on the other side of the projection. A fluid exchange between inside and outside of an area between the stop surface and armature is via a path through the inner surface, conduit, and outer surface when the armature is in contact with the stop surface at the projection plane.
