Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei den bisher bekannten pneumatischen Farbzerstäubern wird als Abschlußkörper für die Austrittsöffnung der Farbe eine unter Federdruck stehende Vollnadel angewendet. Das Preßluftventil ist bei den bekannten Apparaten in der Luftzuleitung angeordnet und wird in der Regel auch von dem Hebel geöffnet und geschlossen, der das Nadelventil bewegt. Diese Apparate eignen sichIn the case of the pneumatic paint atomizers known so far, the closing body for A spring-loaded full needle is applied to the paint outlet. The compressed air valve is arranged in the known apparatus in the air supply line and is usually also opened and closed by the lever that controls the needle valve emotional. These devices are suitable
ίο demnach nicht zur Ausführung genauer Tuschzeichnungen, da sie den Farbstrahl zu sehr ausbreiten und außerdem das öffnen und Schließen der beiden Ventile zu verschiedenen Zeitpunkten erfolgt. Der' größte Nachteil dieser Apparate besteht aber darin, daß die Farbe bei ihrem Durchtritt durch das Ventil die Dichtflächen des letzteren energisch bestreicht und stellenweise abschleift, so daß schon nach kurzer Zeit das Farbventil nur noch mangelhaft schließt und die Leistung des Apparates bedeutend nachläßt.ίο therefore not for the execution of exact ink drawings, because they spread the paint beam too much and also open that and Closing of the two valves takes place at different times. The main drawback This apparatus consists in the fact that the color as it passes through the valve the sealing surfaces of the latter are vigorously brushed and abraded in places so that after a short time the paint valve only closes poorly and the performance of the apparatus decreases significantly.
Apparate, bei denen die Farbe auch in vollem Strahl austritt, sind nun zwar bekannt, jedoch unterscheidet sich die den Gegenstand der Erfindung bildende Ausführungsform dadurch, daß die hohle Farbzuführungsleitung verschiebbar ist und. zum Abschluß der Luftdüse dient. :'Apparatuses in which the paint also emerges in full jet are now known, but the one differs Embodiment forming the subject of the invention, characterized in that the hollow paint supply line is movable and. serves to complete the air nozzle. : '
Bei dem auf der Zeichnung im Längsschnitt dargestellten Gegenstand der vorliegenden Erfindung ist statt der Vollnadel eine Hohlnadel c verwendet, deren hohler Schaft^ eine seitliche Öffnung k besitzt, die mit der Ausflußöffnung i des Farbbehälters a in Verbindung gebracht werden kann, indem sie mittels des Hebels e entgegen dem Drucke der Feder r auf dem Schaft s zurückgezogen wird. Die Farbe nimmt ihren Weg durch die Nadel b und tritt aus dieser in Form eines Kernstrahles aus der Längsbohrung des Teiles c aus. In Gestalt eines ringförmigen Strahles tritt nunmehr nur noch die Luft zwischen der Außenfläche der Hohlnadel c und der Innenfläche des Gehäuses aus der Düse aus, welche, da die Luft weder feste, noch das Material angreifende flüssige Körper mit sich führt, keiner abschleifenden Wirkung auf ihrer Dichtfläche ausgesetzt ist. Bei diesem Apparat ist in der Luftzuleitung ο, η demnach auch ein Ventil entbehrlich.In the subject of the present invention shown in the drawing in longitudinal section, a hollow needle c is used instead of the full needle, the hollow shaft ^ has a lateral opening k , which can be brought into connection with the outflow opening i of the paint container a by means of the lever e is withdrawn against the pressure of the spring r on the shaft s. The paint takes its way through the needle b and emerges from this in the form of a core beam from the longitudinal bore of the part c . In the form of an annular jet, only the air now emerges from the nozzle between the outer surface of the hollow needle c and the inner surface of the housing, which, since the air carries neither solid nor the material attacking liquid bodies with it, no abrasive effect on its Sealing surface is exposed. In this apparatus, a valve is therefore also unnecessary in the air supply line ο, η.
Außerdem findet das öffnen und Schließen des Farbauslaßventiles mit dem des Luftventiles gleichzeitig statt. Nichtsdestoweniger ist ebenfalls nur ein Hebel erforderlich, der beide Ventile gleichzeitig bewegt. Da sich die Dichtflächen des Nadelventiles nicht mehr abnutzen, so kann auch nicht mehr der lästige Übelstand eintreten, daß die Nadel selbst infolge Abnutzung mehr oder weniger aus der Düse hervorragt und dadurch ein genaues Arbeiten verhindert.In addition, the opening and closing of the paint outlet valve takes place with that of the air valve at the same time. Nevertheless, only one lever is required, the both valves moved at the same time. Since the sealing surfaces of the needle valve are no longer wear out, so the annoying disadvantage that the needle can no longer occur even more or less protrudes from the nozzle as a result of wear and tear and thereby a prevents precise work.
Die Kernform des Farbstrahles ermöglicht gleichfalls eine genauere Ausführung der Zeichnung, als dies mit den Apparaten möglich war, bei denen die Farbe in ringförmigem Strahl austritt.The core shape of the color jet also enables a more precise execution of the Drawing when this was possible with the apparatuses in which the color in ring-shaped Beam emerges.

Um das Eintreten von Preßluft in den Farbbehälter längs der Außenwand der Röhre b und der Innenwand des Körpers χ zu verhindern, kann ein aus Dichtungsmaterial bestehender Ring in die zwischen den Stücken h und \ sowie der Außenwand von b entstehende Ringnut eingelegt werden. Um eine Verdrehung der Hohlnadel b und damit eine Verdrehung der Öffnung k zur Öffnung i zu verhüten, ist in die Hohlnadel b ein Schaft d eingeschraubt, der in eine vierkantige. Spindel s endet, die in einer ebensolchen Öffnung des Quersteges u geführt ist. Eine Querwand Z in-der Hohlnadel b schließt letztere rückwärts ab.To prevent compressed air from entering the paint container along the outer wall of the tube b and the inner wall of the body χ , a ring made of sealing material can be inserted into the ring groove between the pieces h and \ and the outer wall of b. In order to prevent a twisting of the hollow needle b and thus a twisting of the opening k to the opening i , a shaft d is screwed into the hollow needle b , which is screwed into a square. Spindle s ends, which is guided in such an opening of the crossbar u. A transverse wall Z in the hollow needle b closes the latter from the rear.
