Abstract
An electromagnetically actuable valve having an axial fuel inflow, in which the opening path of the valve closing element is limited by a stop rod device which permits a controlled opening stroke of the valve closing element as a function of a position of the valve needle. The stop rod is arranged concentrically with respect to the valve longitudinal axis so that the stop rod touches the valve closing element in the opening position of the valve and thus limits its opening stroke. The stop rod is mounted in a flow bore of a core of the valve by means of a displacement sheath. The design of the stop device is particularly suitable for fuel injection valves.
