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.
