Title: Fuel injection valve

Abstract: A fuel injection valve is is described. The fuel injection valve includes a swirl disk downstream from a valve seat, the swirl disk being made of at least one metallic material, having at least two swirl channels opening into a swirl chamber, and in which all layers are adheringly deposited directly one on top of the other by electroplating (multilayer electroplating). A perforated spray disk having an outlet opening shaped so that it directly influences the flow of the fuel exiting through the outlet opening of the swirl disk is arranged directly downstream from the swirl disk. The fuel injection valve is particularly well suited for direct injection of fuel into the combustion chamber of a compressed mixture externally ignited internal combustion engine.
