Description
Vorliegende Erfindung betrifft eine Neuerung an Farbventilen für Luftmalapparate, insbesondere für solche nach Patent 222399. Läßt sich auch die Abnutzung der Ventilnadel an solchen Ventilen naturgemäß nicht vermeiden, so ist es doch unbedingt wünschenswert, daß diese an keiner Stelle deformiert wird, soweit sie bewegliche Teile zu tragen hat, weil sonst die Erscheinung auftritt, daß, wenn die Nadel infolge natürlichen Verschleißes an der Spitze abgeschliffen ist und weiter nach vorn gestellt werden muß, die an der Nadel entstandenen Deformationen ein sicheres Einstellen in die neue Lage zur Unmöglichkeit machen. Insbesondere muß darauf Rücksicht genommen werden, daß die Nadel weder einen Bund, einen Ring noch ein Gewinde trägt und doch die von ihr getragenen Ventilteile mit der Nadel so verbunden werden können, daß die Ventilteile samt der Nadel auf eine ganz bestimmte Länge eingestellt wrerden können, ohne daß nachträgliche Verschiebungen möglich sind. Zu diesem Zweck ist das die Ventilnadel 1 umgebende Luftventil 2 so ausgestaltet worden, wie auf der Zeichnung dargestellt. Dies stellt hierbei einen Hohlkörper dar, der am rückwärtigen Ende abgesetzt ist, seitlich einen Schlitz und am vorderen Ende einen Bund 3 trägt. Schiebt man nun das Ventil 2 auf die Nadel 1, so setzt es sich mit federnder Kraft auf ihr fest. Hat man die Nadel 1 auf die richtige Stelle eingestellt, so hält man diese Arbeitslage dadurch fest, daß man die Klemmschraube 4 auf den Ventilkörper 2 aufschraubt. Soll nach Abnutzung der Nadelspitze diese weiter nach vorn eingestellt werden, so lockert man die Schraube 4, schiebt die Nadel etwas nach und hält sie in der neuen Arbeitslage wieder fest. 6 ist eine Feder, die in bekannter Weise das Luftventil schließt, und 5 ist die Feder, die von 6 beeinflußt wird, so daß sie zuerst das Farbventil verschließt und dann erst das Luftventil.The present invention relates to an innovation in color valves for air painting apparatus, in particular for those according to patent 222399. If the wear and tear of the valve needle on such valves cannot of course be avoided, it is absolutely desirable that it is not deformed at any point if it has moving parts has to bear, because otherwise the phenomenon occurs that if the needle is ground off at the point due to natural wear and has to be moved further forward, the deformations that have arisen on the needle make safe adjustment to the new position impossible. In particular this into consideration must be taken that the needle not a covenant, a ring still carries a thread, yet which can be joined by her worn valve parts with the needle so that the valve parts including the needle in a certain length set w r ground can without subsequent shifts being possible. For this purpose, the air valve 2 surrounding the valve needle 1 has been designed as shown in the drawing. This represents a hollow body which is offset at the rear end, has a slot on the side and a collar 3 at the front end. If the valve 2 is now pushed onto the needle 1, it will become firmly attached to it with a resilient force. Once the needle 1 has been set to the correct position, this working position is held by screwing the clamping screw 4 onto the valve body 2. If the needle point is to be adjusted further forwards after the needle point has been worn, loosen the screw 4, push the needle a little further and hold it in the new working position again. 6 is a spring which closes the air valve in a known manner, and 5 is the spring which is influenced by 6 so that it closes the paint valve first and then the air valve.
