Abstract

Munnstykket omfatter et indre kammer (8) tilført trykkfluid, som står i kommunikasjon med en ringformet utløpsåpning (5). Det omfatter en indre kanal (2) sentrert på den ringformede åpningens akse og hvis diameter korresponderer hovedsakelig med diameteren til den ringformede åpningen, idet kanalen tilveiebringer en dobbelstrømning rundt munnstykket og fluidfilmen som kommer ut av åpningen. Munnstykket kan benyttes for å sprøyte alle typer fluider: vann, drivstoff, bruks-områder som involverer høye strømningshastigheter i størrelsesorden 5 til 60 mpr. time, og likevel i svært fine dråper. Sprøyteanordningen utstyrt med et slikt munnstykke omfatter fortrinnsvis to motroterende vifter (22 og 23). Munnstykket (1) kan også være utstyrt med kimdannere (70) anordnet på dets periferi for å bevirke frødannelse av vann/luftblandingen for , produksjon av kunstig snø. Den beskrevne sprøyte-anordningen har fordel av å være spesielt kompakt.The nozzle comprises an inner chamber (8) supplied with pressure fluid, which is in communication with an annular outlet opening (5). It comprises an inner channel (2) centered on the axis of the annular opening and whose diameter corresponds mainly to the diameter of the annular opening, the channel providing a double flow around the nozzle and the fluid film coming out of the opening. The nozzle can be used to spray all types of fluids: water, fuel, application areas involving high flow rates in the order of 5 to 60 mpr. hour, and yet in very fine drops. The spray device equipped with such a nozzle preferably comprises two counter-rotating fans (22 and 23). The nozzle (1) can also be equipped with nucleators (70) arranged on its periphery to cause seed formation of the water / air mixture for the production of artificial snow. The described spray device has the advantage of being particularly compact.
