Fuel injection valve
摘要:
A fuel injection valve having a swirl disk, located downstream from a valve seat (15), that is made of at least one metallic material and has at least two swirl channels emptying into a swirl chamber, with all layers being built up by electrodeposition (multilayer electroplating) so that they adhere firmly to each other. The swirl disk has an upper layer that includes multiple material areas separated from each other by opening structures. The material areas of the swirl disk rest against a valve seat body containing the valve seat. The fuel injection valve is especially suitable for injecting fuel directly into the combustion chamber of a mixture-compressing internal combustion engine with externally supplied ignition.
