Perforated disk or atomizing disk and an injection valve with a perforated disk or atomizing disk

An injection valve having a longitudinal valve axis, comprising:

• a valve seat surface;
• a valve closing member cooperating with the valve seat surface;
• and
• a perforated disk composed of at least one metallic material and situated downstream from the valve seat surface, the perforated disk including:
• a single part with at least one layer having a passage for facilitating a flow of a fluid, the passage extending through the single part, the single part including a plurality of functional plates, the plurality of functional plates including an upper functional plate and a lower functional plate, the upper functional plate including at least one inlet opening of the passage, the lower functional plate including at least one outlet opening of the passage, the single part including at least one gas supply opening in communication with the passage;
• wherein each of the plurality of functional plates is electrodeposited onto each adjacent functional plate in an electrodepositing operation to thereby form the single part.

• a valve seat body including the valve seat surface for connecting to a further outlet opening in a downstream direction;
• and
• a perforated disk holder clamping the perforated disk to the valve seat body;
• wherein each of the plurality of functional plates is electrodeposited onto each adjacent functional plate in an electrodepositing operation to thereby form the single part;
• wherein the upper functional plate is disposed in a particular area of the perforated disk, the particular area having a first outer diameter;
• wherein the lower functional plate is surrounded by a base area of the perforated disk, the base area having a second outer diameter, the first diameter being smaller than the second diameter;
• and
• wherein the particular area extends into the further outlet opening, and the base area is disposed against a lower end face of the valve seat body.
