Abstract: In an electromagnetically actuable fuel injection valve for fuel injection systems of internal combustion engines, including a of valve housing, magnetic coil and a valve closing element which, when the magnetic coil is excited, lifts off from a valve seat and releases fuel, to arrange in the outlet area of the fuel includes at least one diaphragm which is capable of oscillation and forms with other parts of the valve at least one (annular) metering gap and which can be excited solely by the pressure of the fed-in fuel to experience resonance oscillations so that a high-frequency modulation of the fuel lamella emitted from the (annular) metering gap, and a spray angle, is produced.

Abstract: An electromagnetically actuated fuel injection valve for a fuel injection system of an internal combustion engine includes a valve housing, a magnet coil, and a valve needle. When the magnet coil is excited, the valve needle lifts off from its valve seat and allows fuel to pass. Downstream after the valve seat of the valve needle, two annular peripheral knife-edges face one another to generate one or more conical fuel lamellae extending in substantially laminar fashion. An annular metering gap is formed by the two knife-edges located close together such that the lower annular peripheral edge of the metering gap includes a stationary spray plate or a valve needle end piece.
