Abstract: An atomizer disk is composed of at least one metallic material, is configured with at least one inlet opening in an upper cover layer and at least one outlet opening in a lower base layer, and has at least two swirl channels that terminate into a swirl chamber, the swirl chamber being provided in a middle swirl generation layer. Through the inlet opening and the swirl channels, two flows of different natures (biflux) enter the swirl chamber. All the layers of the atomizer disk are built up directly onto one another by electroplating metal deposition (multilayer electroplating). The atomizer disk is suitable for use in a fuel injection valve, in particular a high-pressure injection valve for direct injection of fuel into a combustion chamber of a mixture-compressing, spark-ignited internal combustion engine.
