Process for the preparation of micro-valve and micro valve

(57) Abstract: microvalve of the present invention (1) is made from electromagnetic drive unit (2) and the valve lower portion of the multi-layer type (17) which is produced separately from one another and fixedly coupled to each other . The valve lower portion (17), at least one Jikyokuko (18) and axially movable valve closing element (20), and surrounds the component of said axial movable microvalve (1) at least partially and a casing (12) to be. The valve lower portion (17) is configured to sequentially vertically by metal Electroplating deposition (multilayer Electroplating method). Microvalve of the present invention is suitable for use in a fuel injection system of an internal combustion engine.
