US 5,766,441 A · Method for manfacturing an orifice plate

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.

Dependent claims

A method for manufacturing an orifice plate, comprising the steps of:

(a) providing a bottom layer including at least one outlet opening;
(b) providing at least one interior layer above the bottom layer, the at least one interior layer including at least one conduit, the at least one conduit connected to the at least one outlet opening;
and
(c) providing a top layer above the at least one interior layer, the top layer including at least one inlet opening, the at least one inlet opening connected to the at least one conduit and disposed offset from the at least one outlet opening;
wherein the bottom layer, the at least one interior layer, and the top layer are each provided by an electroplating metallization directly on top of one another.
