Description

Düse für Spritzpistolen (Zeichnung P 349) Die Erfindung betrifft eine Düse zum Spritzen von Farben, Email, Unterbodenschutzmaterial und dergl.Nozzle for spray guns (drawing P 349) The invention relates to a Nozzle for spraying paints, enamel, underbody protection material and the like.

Aufgabe dieser Erfindung ist es, mit einer derartigen Düse dünnflüssige und mehr oder weniger hochviskose oder pastöse Medien in einfachster Weise nebelarm und mit scharfer Randbegrenzung zu verspritzen und ein Zuwachsen des Düsenmundstückes zu vermeiden.The object of this invention is to produce low-viscosity with such a nozzle and more or less highly viscous or pasty media in the simplest way with little fog and to be sprayed with a sharp border and an overgrowth of the nozzle mouthpiece to avoid.

Zur Lösung dieser Aufgabe erfolgt bei mit Spritzluft betriebenen Pistolen die Mischung von Material und Luft in einer sogenannten Mischkammer, die aus Materialdüse und Mundstück gebildet wird. Die Randbegrenzung des fächerförmigen oder kegelförmigen oder anderweitig geformten Strahles erfolgt durch einen sogenannten Luftvorhang, der die Randstrahlen bündelt. Dieser Luftvorhang entsteht durch spezielle, im Düsenmundstück enthaltene Kanäle, durch die Preßluft hindurchgeleitet wird.The solution to this problem is carried out with spray guns operated with spray air the mixing of material and air in a so-called mixing chamber, which consists of a material nozzle and mouthpiece is formed. The border of the fan-shaped or conical or otherwise shaped beam takes place through a so-called air curtain, which bundles the marginal rays. This air curtain is created by special, in the nozzle mouthpiece contained channels through which compressed air is passed.

Eine die Austrittsöffnung umgebende Flächeist schneidenförmig ausgebildet und dient dem zu verspritzenden Medium als Abrißkante, wodurch eine Materialablagerung und ein damit verbundenes allmähliches Zuwachsen der Austrittsöffnung mit der Folge einer Strahlveränderung unterbunden wird.A surface surrounding the outlet opening is designed in the shape of a cutting edge and serves as a tear-off edge for the medium to be sprayed, creating a deposit of material and an associated gradual widening of the outlet opening with the result a beam change is prevented.
