摘要:
A swirl disk is composed of at least one metallic material, and is configured as having at least one intake area and at least one outlet orifice, the at least one outlet orifice being introduced in a lower base layer, and having at least two swirl channels emptying into a swirl chamber, the swirl chamber being provided in a central swirl-producing layer. An upper layer is configured as a cover layer, which over its entire cross-sectional surface represents a closed layer without orifice contours. All the layers of the swirl disk are directly built up on top of each other using electroplating metal deposition (multilayer electroplating). The swirl disk is suitable for a use in a fuel injection valve, in particular in a high-pressure injection valve for directly injecting the fuel into a combustion chamber of a mixture-compressing, external-ignition internal combustion engine.
