METHOD OF MANUFACTURING DISC WITH HOLES Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: method is used for valve nozzles in fuel injection systems, for painting nozzles, inhalers and in printing devices with ink recording. Disc with holes has multi-layer structure with full axial passage for fluid medium. The passage includes inlet holes, outlet holes 38 and at least one channel 42 positioned between the holes. Layers 35, 37 and 40 of disc 23 are produced by the method of polylayer electroplating. The method allows manufacture of discs which form jets in compliance with desirable geometry, for example, S and Y forms, tapered and unusual form of jet cross-section (cross, rectangle, triangle, circle). EFFECT: higher efficiency. 12 cl, 33 dwg
