Title:
【発明の名称】オリフィス処理方法
Document Type and Number:
Japanese Patent JPH04502886
Kind Code:
A
Abstract:
A method of processing an orifice in a structure to attain a precise predetermined flow resistance through said orifice. Undersized orifices are machined by either electrochemical, chemical or electric discharge machining, while oversized orifices are electroplated, electroless plated or vapor deposition coated, such that the processing fluid, i.e. the electrolyte, corrosive fluid, dielectric or carrier gas as used in the machining, plating or coating process is passed through said orifice during said processing at a predetermined fixed pressure while measuring the dynamic flow resistance of said processing fluid through said orifice until said dynamic flow resistance is equal to that desired.
