Farbzerstäuber. Patentiert im Deutschen Reiche vom 12. Juni 1913 ab. Paint atomizer. Patented in the German Empire on June 12, 1913.

Gegenstand der Erfindung ist ein Farbzerstäuber, bei welchem die Ventilnadel bis fast an ihr hinteres Ende in einer dichten Führung geführt ist, so daß sie die an der Nadel entlang nach hinten fließende Farbe hindert, in die Bewegungsvorrichtungen der Ventilnadel zu gelangen, sie vielmehr nach außen ableitet, wo sie mit Leichtigkeit entfernt werden kann. Ein Ausführungsbeispiel der Erfindung ist durch dieThe invention relates to a paint atomizer in which the valve needle is almost up to it rear end is guided in a tight guide so that they follow along the needle paint flowing at the back prevents the valve needle moving devices from entering, rather, it derives to the outside, where it can be removed with ease. An embodiment the invention is through the

ίο Zeichnung in Fig. ι im Aufrißschnitt und in Fig. 2 im Querschnitt dargestellt. Der Farbzerstäuber hat äußerlich die bekannte Pistolenform. Am Hauptkörper B ist der Griff α befestigt, durch den die Preßluft zugeleitet wird, während die Farbe in dem Gefäß A enthalten ist, das oben am Hauptkörper B befestigt ist. Am vorderen Ende des Hauptkörpers B befinden sich die Farbdüse f und die Luftdüse c. Die den Farbzufluß regelnde Ventilnadel ν ist so lang, daß ihr hinteres Ende hinten aus dem Hauptkörper B herausragt. , Der hintere Teil des Hauptkörpers B ist ausgebohrt und enthält ein Rohr D, das vorn dicht mit dem Hauptkörper verbunden ist und hinten aus dem Hauptkörper ein Stück herausragt. Dieses Rohr D kann auch, wie dies in Fig. 1 dargestellt ist, mit dem Hauptkörper B aus einem Stück sein. In dem Hauptkörper und dem Rohr D ist die Ventilnadel r geführt, und daίο drawing shown in Fig. ι in elevation section and in Fig. 2 in cross section. The paint atomizer has the familiar pistol shape on the outside. On the main body B , the handle α is attached, through which the compressed air is supplied, while the paint is contained in the vessel A, which is attached to the top of the main body B. At the front end of the main body B, there are the paint nozzle f and the air nozzle c. The valve needle ν regulating the flow of paint is so long that its rear end protrudes from the main body B at the rear. The rear part of the main body B is bored out and contains a pipe D which is tightly connected to the main body at the front and protrudes slightly from the rear of the main body. This tube D can also, as shown in FIG. 1, be in one piece with the main body B. In the main body and the pipe D , the valve needle r is guided, and there

30. die Führung keinerlei Unterbrechungen besitzt, kann die an der Nadel entlang nach hinten fließende Farbe erst zu dem hinteren, aus dem Hauptkörper B herausragenden Ende der Ventilnadel austreten. Die Bewegung der Ventilnadel geschieht durch den Hebel«; dieser ist auf der Welle k befestigt, die im Hauptkörper B drehbar gelagert ist, und auf der zwei Hebel i befestigt, sind, die das Rohr D gabelförmig umfassen. Wenn dej Hebel χ nach dem Handgriff α zu bewegt wird, drücken die beiden Hebel * gegen den das Rohr D umgebenden, im Hauptkörper B verschiebbaren Ringkörper / und verschieben ihn nach hinten. Hinter dem Ringkörper I befindet sich eine Feder m, und hinter der Feder m wieder ein das Rohr D umgebender, im Hauptkörper B verschiebbarer Ringkörper η. Dieser Körper η ist mit der Ventilnadel r an deren hinterem, aus dem Hauptkörper herausragenden Ende verbunden und wird durch die Feder 0, die sich gegen die im Hauptkörper befestigte Büchse w stemmt, für gewöhnlich nach vorn gedrückt, so daß die Ventilnadel das Farbventil schließt. Die gesamte Bewegungsvorrichtung für die Ventilnadel liegt also in dem Ringraum zwischen dem Hauptkörper B und dem Rohr D dicht eingeschlossen und kann weder von der innerhalb des Rohres an der Ventilnadel entlang nach hinten fließenden Farbe noch von der aus dem Farbbehälter verschütteten Farbe verschmiert werden. Wenn der Körper I durch die Hebel i nach hinten gedrückt wird, wird zunächst die Feder η zusammengedrückt, dann trifft der Körper / an den Körper η an und drückt diesen nach hinten, wodurch die Färbnadel zurückgezogen wird. Während der Körper I die Feder m zusammendrückt, noch bevor er an den Körper η antrifft, ist er an die Kugel y angetroffen und hat diese nach unten gedrückt. Hierdurch ist das Luftventil p ge-30. the guide has no interruptions, the paint flowing backwards along the needle can only escape to the rear end of the valve needle protruding from the main body B. The valve needle is moved by the lever «; this is fastened on the shaft k , which is rotatably mounted in the main body B , and on which two levers i are fastened, which encompass the tube D in the shape of a fork. When the lever χ is moved towards the handle α , the two levers * press against the ring body / surrounding the tube D , which can be moved in the main body B , and move it to the rear. Behind the ring body I there is a spring m, and behind the spring m there is another ring body η which surrounds the tube D and is displaceable in the main body B. This body η is connected to the valve needle r at its rear end protruding from the main body and is usually pushed forwards by the spring 0 which is pressed against the bushing w fixed in the main body, so that the valve needle closes the paint valve. The entire movement device for the valve needle is thus tightly enclosed in the annular space between the main body B and the tube D and cannot be smeared either by the paint flowing backwards along the valve needle inside the tube or by the paint spilled from the paint container. When the body I is pushed backwards by the lever i , the spring η is first compressed, then the body / hits the body η and pushes it backwards, whereby the dyeing needle is withdrawn. While the body I compresses the spring m before it hits the body η , it has hit the ball y and has pressed it downwards. As a result, the air valve p is

öffnet worden, und die durch den Stutzen u eintretende Luft ist durch das Ventil p und den Kanal q in den Ringkanal h und von dort durch die Kanäle g und e in die Luftdüse c gelangt.has been opened, and the air entering through the nozzle u has passed through the valve p and the channel q into the annular channel h and from there through the channels g and e into the air nozzle c .

Um die Bewegung der Nadel r in der langen Führung zu erleichtern, kann die Nadel so ge-, staltet werden, daß sie nicht mit ihrer ganzen Fläche an der Führung anliegt; sie kann beispielsweise, wie Fig. τ zeigt, mit Längsriefen versehen werden.In order to facilitate the movement of the needle r in the long guide, the needle can be designed in such a way that its entire surface does not lie against the guide; it can, for example, as FIG. τ shows, be provided with longitudinal grooves.
