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.
