Abstract

Es wird eine einfache, handliche und betriebssichere Vorrichtung vorgeschlagen, mit der ein Fluid, z.B. flüssige Farbe, auf einen zu bearbeitenden Gegenstand aufgesprüht werden kann, wobei die Fördergeschwindigkeit des dem Zentrum der Sprühglocke zugeführten Fluids bei Eintritt in die Glocke auf nahezu Null verzögert wird, dann die Geschwindigkeit dadurch erhöht wird, daß es durch die Glocke auf 15.000 bis 60.000 UPM beschleunigt und anschließend von der Sprühkante der Glocke abgeschleudert und dem zu beschichtenden Gegenstand zugeführt wird. It becomes a simple, handy and reliable Device proposed with which a fluid, e.g. liquid Paint sprayed onto an object to be processed can be, the conveying speed of the Center of fluid supplied to spray bell upon entry into the bell is delayed to almost zero, then the Speed is increased by the fact that it is Bell accelerated to 15,000 to 60,000 rpm and then thrown off the spray edge of the bell and is supplied to the object to be coated.
