Description

Die Erfindung betrifft Farbzerstäuber, bei denen dem Behälter, aus dem die Farbe entnommen wird, Druckluft zugeführt wird, und bezweckt, eine Anpassung des im Farbbehälter herrschenden Druckes an den Druck, welcher in der Spritzdüse auftritt, zu verhindern, daß der Druck im Farbbehälter zu hoch wird, ohne daß Unzuträglichkeiten eintreten, wie es bei bekannten Farbzerstäubern der Fall ist, bei' denen die zum Farbbehälter führende Luftleitung mit einer Luftaustrittsöffnung versehen ist, durch die bei gewisser Lage des Farbbehälters Farbe austreten kann.The invention relates to paint atomizers, in which the container from which the paint is taken is, compressed air is supplied, and the purpose of an adaptation of the in the paint container prevailing pressure to prevent the pressure that occurs in the spray nozzle, that the pressure in the paint container becomes too high without inconveniences occurring, as is the case with known paint atomizers is the case where the air line leading to the paint container has an air outlet opening is provided, through which paint can escape with a certain position of the paint container.

Die Erfindung besteht darin, daß der Luftkanal für die Entnahme der dem Farbbehälter zuzuführenden Druckluft am vorderen Teile der Spritzdüse angeordnet ist, so daß eine Luftströmung mit auf Spritzdüse und Farbbehälter verteiltem Druckgefälle gebildet wird.The invention consists in that the air duct for the removal of the paint container to be supplied compressed air is arranged at the front parts of the spray nozzle, so that a Air flow is formed with a pressure gradient distributed over the spray nozzle and paint container will.

Die Zeichnung stellt den Erfmdungsgegenstand in drei Ausführungsbeispielen dar. Bei der einfachen Ausführung nach Abb. 1 und 2 wird die Druckluft dem Farbbehälter 4 durch das Rohr 3 und den Kanal 2 zugeführt. Die Luft für den Farbbehälter wird in der Nähe der Ausströmlöcher der Flachstrahlkanäle S des drehbaren Luftkopfes 8 und des oder der Ausströmlöcher 6 der Luftdüse 7 entnommen. Durch das Ausströmen der Luft findet an dieser Stelle eine Reduzierung des Druckes der durch Kanal 11 zugeführten Preßluft statt. Diese auf geringeren Druck gebrachte Luft wird durch das Rohr 3 und den Rückleitungskanal 2 in den Farbbehälter 4 geleitet. Der Farbbehälter 4 ist allseitig verschlossen, demzufolge übt die Preßluft einen Druck auf die im Farbbehälter 4 befindliche Flüssigkeit, gleich welcher Art, aus, wodurch diese in bekannter Weise durch das Steigrohr ι ο und die Farbdüse 9 dem Preßluftkegel zugeführt wird. Der Hauptstrom der Preßluft wird durch den Zugangskanal Ii der Luftdüse 7 zugeführt und durch die Verteilerscheibe r gleichmäßig in derselben verteilt.The drawing represents the subject matter of the invention in three exemplary embodiments. In the simple version according to Fig. 1 and 2, the compressed air is fed to the paint container 4 fed through the pipe 3 and the channel 2. The air for the paint container is in the Proximity of the outflow holes of the flat jet channels S of the rotatable air head 8 and the or taken from the outflow holes 6 of the air nozzle 7. By the outflow of air takes place at this point a reduction in the pressure of the channel 11 supplied Compressed air instead. This brought to lower pressure air is through the pipe 3 and the return duct 2 is routed into the paint container 4. The paint container 4 is on all sides closed, consequently the compressed air exerts a pressure on the liquid in the paint container 4, of whatever kind, whereby this in a known manner through the riser ι ο and the paint nozzle 9 to the compressed air cone is fed. The main stream of compressed air is through the access channel Ii supplied to the air nozzle 7 and through the distributor disc r uniformly in the same distributed.

Abb. 3 und 4 zeigen eine Ausführungsform, bei der der Kopfteil 3" des Farbzuführungsrohres am vorderen Ende mit Führungskonus für die Luftdüse 1J" versehen ist sowie vier über Kreuz eingeschnittene Luftkanäle 13 hat, mit welchen der horizontale bzw. vertikale Flachstrahl, und zwar durch Drehen der Luftdüse 70, erzeugt wird. Die Druckluft nach dem Farbgefäß strömt hier durch den oder die Kanäle 14 in das Innere des Kopfteiles 3*, von da in den Rückleitungskanal 2fl. und in den Farbbehälter.Fig. 3 and 4 show an embodiment in which the head part 3 "of the paint supply tube is provided at the front end with a guide cone for the air nozzle 1 J" and has four cross-cut air channels 13, with which the horizontal and vertical flat jet, namely by turning the air nozzle 7 0 is generated. The compressed air after the paint vessel flows here through the channel or channels 14 into the interior of the head part 3 *, from there into the return channel 2 fl . and in the paint container.

Abb. s und 6 zeigt eine Ausführungsform, 6a bei der der Kopfteil in Form einer Übersteckdüse γ mit Verteilerlochscheibe ib ausgebildet ist. Die Übersteckdüse γ ist über die eigentliche Farbdüse 9* gesteckt und wird durch die Luftdüse 7* nach hinten luftdicht abgeschlossen. Die Übersteckdüse 3* ist am vorderen Ende etwas weiter als der Durchmesser der Farbdüse 9* so daß zwischen der Farbdüse gb und der Übersteckdüse 3* ein ringförmiger Raum 15 gebildet wird. Durch diesen Ringraum 15 fließt die Druckluft in den Rückleitungskanal 2b und dann in den Farbbehälter.Fig. S and 6 shows an embodiment, 6a in which the head part is designed in the form of a plug-in nozzle γ with orifice plate i b . The slip-on nozzle γ is placed over the actual paint nozzle 9 * and is sealed off airtight at the rear by the air nozzle 7 *. The plug-in nozzle 3 * is slightly wider at the front end than the diameter of the paint nozzle 9 * so that an annular space 15 is formed between the paint nozzle g b and the plug-in nozzle 3 *. The compressed air flows through this annular space 15 into the return duct 2 b and then into the paint container.
