DISK WITH HOLES FOR VALVE NOZZLES Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed invention can be used in valve nozzles of fuel injection systems, painting nozzles, inhalers, printing devices with ink recording and in freeze drying, and also for injection or spraying liquids and for atomizing medicines. Holes in disk form axial passage for fluid medium made up of intake holes, outlet holes and at least one channel placed in between. At least three functional planes of disk with holes with corresponding specific hole structure are formed by galvanizing (multiple layer galvanizing). One galvanically deposited layer of disk with holes can have one or several functional planes. EFFECT: reduced discharge of exhaust gases and consumption of fuel. 20 cl, 33 dwg
