466 9B2466 9B2 Die Erfindung stellt eine Düseneinrichtung für Farbzerstäuber dar, welche durch doppelte D rehstrahl wirkung bei niedrigem Luftdruck eine feine Zerstäubung gibt. Dies wird dadurch erreicht, daß auf eine innere Farbdüse eine Kappe gesetzt wird, welche die Luftdüse bildet und am Boden spiraüg gefräste Nuten trägt. Die feine Zerstäubung wird dadurch erhöht, daß- auf diese Kappe nochThe invention provides a nozzle device for paint atomizer, which by double Rotary jet effect gives a fine atomization at low air pressure. This is because of this achieves that a cap is placed on an inner paint nozzle, which the air nozzle forms and carries spiral milled grooves on the bottom. The fine atomization will increased by that- on this cap still ίο eine zweite Kappe mit in entgegengesetzter Drehrichtung gefrästen Nuten geschraubt wird, so daß dem in die erste Drehung versetzten Strahl eine entgegengesetzte Drehung aufgezwungen wird und dadurch die Flüssigkeit äußerst fein und breit zerstäubt wird. Gleichzeitig kann diese Vorrichtung so verwendet werden, daß man durch die erste Düse anstatt Luft die zu zerstäubende Farbe unter Druck fließen läßt und in die darüber geschraubte zweite Düsenkappe den Luftstrom leitet. Es wird hiermit erreicht, daß der kreiselnde Farbstrahl von der Luftwirkung mehr zusammengehalten wird und, da die Drehwirkung der Luft um den Farbstrahl stattfindet, die Bildung von umherfliegendem Staub bedeutend herabgesetzt wird.ίο a second cap with in opposite Direction of rotation milled grooves is screwed, so that the offset in the first rotation Jet is forced to rotate in the opposite direction and thereby the liquid is atomized extremely finely and widely. At the same time, this device can be used in this way that one lets the paint to be atomized flow under pressure through the first nozzle instead of air and into the one above screwed second nozzle cap directs the air flow. It is hereby achieved that the spinning jet of paint is held together more by the action of the air and, since the Rotational action of the air around the jet of paint takes place, the formation of what is flying around Dust is significantly reduced.

In den Zerstäuberkopf (Abb. 1) ist die innere Düseii mit dem geraden Boden/?, welcher auch etwas schräg wie bei Abb. 2a ausgebildet werden kann, eingeschraubt. Auf den Boden der Innendüse ist die Kappen mit den inneren spiraligen Fräsungen i aufgesetzt, k ist die zweite Kappe mit entgegengesetztgerichteten Fräsungen/ (Abb. 5), welche über die erste Kappen geschraubt ist und so die Luftaustritte m und / bildet, b ist der Luftkanal, durch welchen die Druckluft zugeleitet wird und den Weg durch die schraubenförmigen Nuten 1Il und die Öffnung ίί in. die zweite Düsenkappe k nimmt, so daß beide Düsenkappen durch die Luftkanäle h gespeist werden. Die Luftnuten h können durch gerade Nuten ersetzt werden, c ist eine Ventilspindel, welche die Flüssigkeit, die durch den Kanal α ihren Eingang findet und an der Mündung g ihren Austritt nimmt, absperrt. .In the atomizer head (Fig. 1) the inner nozzle with the straight bottom /?, Which can also be designed at an angle as in Fig. 2a, is screwed. The cap with the inner spiral millings i is placed on the bottom of the inner nozzle, k is the second cap with oppositely directed millings / (Fig. 5), which is screwed over the first cap and thus forms the air outlets m and /, b is the air duct is fed through which the compressed air and the way through the helical grooves 1 Il and the opening ίί in. the second nozzle cap k increases, so that the two nozzle caps are fed h through the air channels. The air grooves h can be replaced by straight grooves, c is a valve spindle which shuts off the liquid that enters through the channel α and exits at the mouth g. . Beschreibung zu Blatt 2Description for sheet 2 Blatt 2 zeigt einen Zerstäuber im Querschnitt, bei welchem die Farbe nicht durchdie Mitte der Innendüse der Mündung zügeführt wird, sondern ihren Weg durch die Öffnung if zu den schraubenförmigen Nuten i der Innendüse nimmt und in der Öffnung h ihren Austritt hat. ß ist eine Kappe, welche am Boden in Drehrichtung gefräste spiralige Nutend hat, so daß der hindurchgepreßte Farbstrahl in Kreiselbewegung die Mündung h verläßt und von dem Luftstrom, welcher durch den Kanal δ eintritt und an der Mündung g der Kappe/ seinen Austritt hat, erfaßt wird. Der kreiselnde Farbstrahl wird so mit einer kreiselnden Luftstromhülle umgeben, welche durch die am Boden der Kappe/ in entgegengesetzter Drehrichtung gefrästen Nuten gebildet wird.Sheet 2 shows an atomizer in cross-section, in which the paint is not fed through the center of the inner nozzle of the mouth, but instead makes its way through the opening if to the helical grooves i of the inner nozzle and exits in the opening h. ß is a cap which has a spiral groove end milled in the direction of rotation at the bottom, so that the jet of paint pressed through it leaves the mouth h in a circular motion and is captured by the air flow which enters through the channel δ and has its outlet at the mouth g of the cap will. The spinning ink jet is surrounded by a spinning air flow envelope, which is formed by the grooves milled on the bottom of the cap / in the opposite direction of rotation.
