    摘要: A fuel injection valve is described which has 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). The swirl disk is installed in the valve so that the surface normal to its surface forms an oblique angle other than 0° with the longitudinal valve axis, so that a jet angle &ggr; with respect to the longitudinal valve axis is formed due to the orientation of 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.
