Abstract (en)

[origin: DE19815795A1] The invention relates to an atomizing disc is characterized in that it is comprised of at least one metallic material, has at least one inlet opening (67) in an upper top layer (60), and has at least one outlet opening (69) in a lower base layer (62). In addition, the atomizing disc comprises at least two turbulence ducts (66) which open into a turbulence chamber (68). The turbulence chamber (68) is provided in a middle turbulence generating layer (61). Two different (bi-flux) streams flow into the turbulence chamber (68) via the inlet opening (67) and the turbulence ducts (68). All layers of the atomizing disc (30) are constructed directly on top of one another by means of electrodeposition (multilayer metallizing). The atomizing disc (30) is especially suited for use on a fuel injection valve, especially on a high-pressure injection valve for directly injecting fuel into a combustion chamber of a compound compressed, spark ignition internal combustion engine.
