Abstract: The orifice plate has a complete fluid passageway including inlet orifices, outlet orifices and at least one channel (cavity) disposed between them. The at least three functional levels of the orifice plate, having in each case a characteristic orifice structure, are constructed one on top of the other through electrodeposition (multi-layer electroplating), so the orifice plate is embodied in one piece. Because the orifice plate should be hydraulically unthrottled if the available plate surface is small, the inlet orifices are created with the largest possible circumferences. The orifice plate is particularly suited for use at injection valves, in paint nozzles, inhalers or ink-jet printers, in freeze-drying methods, for spraying or injecting fluids, or for atomizing medications.

Abstract: A method for manufacturing an orifice plate that is built up in multiple layers and includes a complete axial through passage for a fluid. The orifice plate includes inlet openings, outlet openings, and at least one conduit lying between them. The layers or functional planes of the orifice plate are built up on one another by electroplating metal deposition (multilayer electroplating). Orifice plates manufactured in this manner are particularly suitable for use on injection valves in fuel injection systems, in paint nozzles, inhalers, or inkjet printers, or in freeze-drying processes, for spraying or injecting fluids such as beverages.

Abstract: An orifice plate includes a complete axial through passage for a fluid, in particular for a fuel, including inlet openings, outlet openings, and at least one conduit located between them. The inlet and outlet openings are arranged in the orifice plate so that they do not overlap at any point when projected into one plane. This offset of the outlet openings with respect to the inlet openings results in an S-shaped flow profile for the medium, onto which an atomization-promoting turbulence is thus imposed. The orifice plate is particularly suitable for use on injection valves in fuel injection systems, in paint nozzles, or for freeze-drying processes.

The at least three functional planes of the orifice plate, each with a characteristic opening structure, are built up on one another by electroplating metal deposition (multilayer electroplating) . A layer of the orifice plate deposited by electroplating can have one or more functional planes. The orifice plate is particularly suitable for use on injection valves in fuel injection systems, in paint nozzles, inhalers, inkjet printers, for freeze-drying processes, for spraying or injecting liquids, for example beverages, or for atomizing medications.
