ABSTRACT:
An electromagnetically actuatable injection valve, including a nozzle with a shaped end face in combination with a perforated plate through which the fuel flows. The nozzle injection valve has an injection chamber which is defined by a downstream terminal face of the valve closing element and by the perforated plate which is spaced from the nozzle and provided with injection ports. The geometrical embodiment of the injection chamber influences the fuel flow in such a way that a pulse flow vector of the flow penetrates an imaginary jacket face at right angles, so that the injection ports are acted upon substantially by pressure energy. The novel injection valve is especially suitable for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
