PATENTAMTPATENT OFFICE
Bei Spritz vorrichtungen, die Farbe oder andere flüssige oder auch pulverförmige Stoffe verspritzen, benutzt man die Preßluft auch zur Verstellung der Nadelstange, indem man dieser einen Kolben ansetzt, gegen den die Preßluft wirkt. Wenn dabei die Färb- und Luftausströmung gleichzeitig geöffnet wird, so kann Farbe ausfließen, bevor noch der nötige Zerstäuberdruck vorhanden ist.With spray devices, the paint or other liquid or powdery substances spray, the compressed air is also used to adjust the needle bar by this attaches a piston against which the compressed air acts. If doing the coloring and Air outflow is opened at the same time, so paint can flow out before the necessary one Atomizing pressure is present.
ίο Um diesen Mangel zu beseitigen, soll nun nach der Erfindung eine gesonderte Verbindung einerseits zwischen der Luftleitung und dem Luftausströmraum, andererseits zwischen der Luftleitung und dem Zylinder, in welchem der die Nadelstange tragende Kolben sich bewegt, hergestellt werden.ίο To remedy this deficiency, should now according to the invention a separate connection on the one hand between the air line and the air outlet space, on the other hand between the air duct and the cylinder in which the piston carrying the needle bar moves.
Auf der Zeichnung ist der Erfindungsgegenstand im Aufriß veranschaulicht, und zwar zeigen ihnIn the drawing, the subject of the invention is illustrated in elevation, namely show him
Fig. ι in der einen,Fig. Ι in one,
Fig. 2 in der zweiten Endstellung.
Bei dem dargestellten Ausführungsbeispiel wird die Menge der Flüssigkeit aus dem Behälter
α dem Mundstück b zugeführt, dessen achsiale Öffnung durch die Nadelstange c verschlossen
werden soll, die an ihrem vorderen Ende bei d ventilartig ausgebildet ist. Um
das Mundstück b herum und durch die Ringöffnung e strömt die Preßluft aus, die die
Flüssigkeit zerstäubt und mit sich fortreißt. An der Nadelstange c sitzt der Kolben f,
der in dem Zylinder g verschiebbar lagert und unter Wirkung einer Feder h nach vorn gedrückt
wird, wodurch die Nadelstange den Farbzufluß geschlossen hält. Die Spannung dieser Feder kann mittels der Schraube i geregelt
werden. Die Preßluftleitung I, die durch den Handgriff k hindurchgeführt ist, mündet
in dem Steuerzylinder m, in welchem ein Kolbenschieber η unter Einfluß einer Feder
gegen die Abdichtungsfläche 0 gedrückt wird. Der Kolbenschieber η schließt die Eintrittsöffnung der Preßluftleitung Z ab. Durch Anziehen
des Fingerhebels p kann sonach die Eintrittsöffnung freigegeben werden.Fig. 2 in the second end position.
In the illustrated embodiment, the amount of liquid from the container α is fed to the mouthpiece b , the axial opening of which is to be closed by the needle bar c, which is designed like a valve at its front end at d. The compressed air flows out around the mouthpiece b and through the ring opening e , which atomizes the liquid and carries it away with it. On the needle bar c sits the piston f, which is slidably mounted in the cylinder g and is pushed forward under the action of a spring h , whereby the needle bar keeps the flow of paint closed. The tension of this spring can be regulated by means of the screw i. The compressed air line I, which is passed through the handle k , opens into the control cylinder m, in which a piston slide η is pressed against the sealing surface 0 under the influence of a spring. The piston slide η closes the inlet opening of the compressed air line Z. The inlet opening can therefore be opened by pulling the finger lever p.
Nach der Erfindung soll nun die Preßluft so zugeleitet werden, daß sie voll aus dem Mundstück ausströmt, bevor Farbflüssigkeit austreten kann. Umgekehrt muß diese Flüssigkeit bereits abgesperrt sein, bevor der Preßluftstrom abgestellt ist. Zu diesem Zweck ist nun die Stange χ des Kolbenschiebers η mit einer achsialen Bohrung y und entsprechenden Querbohrungen 1 und 2 versehen, die eine Verbindung des Durchgangs q für die Preßluft durch einen Querkanal ζ mit dem Zylinder g herstellen, wenn der Kolbenschieber η vollständig geöffnet ist (Fig. 2).According to the invention, the compressed air is now to be fed in such that it flows fully out of the mouthpiece before color liquid can escape. Conversely, this liquid must already be shut off before the compressed air flow is turned off. For this purpose, the rod χ of the piston valve η is now provided with an axial bore y and corresponding transverse bores 1 and 2, which connect the passage q for the compressed air through a transverse channel ζ with the cylinder g when the piston valve η is fully open (Fig. 2).
Bevor aber dies der Fall ist, kann die Preßluft mit Beginn der Bewegung des KoI-benschiebers η durch die Kanäle r und s nur in den Raum t zwischen den beiden Mundstücken gelangen (Fig. 1). Sie wird also zu dieser Zeit aus der Ringöffnung β ausströmen können, ohne daß sie auf den Kolben f wirkt, und infolgedessen bleibt der Flüssigkeitszufluß noch geschlossen. Ist aber die Endstellung (Fig. 2) des Kolbens / erreicht, dann wirdBut before this is the case, the compressed air can only get into the space t between the two mouthpieces when the piston slide η begins to move through the channels r and s (FIG. 1). It will therefore be able to flow out of the ring opening β at this time without acting on the piston f , and as a result the liquid flow remains closed. But if the end position (Fig. 2) of the piston / is reached, then
durch die Kanäle i, y, 2 und ζ die Preßluft auch in den Zylinder g einströmen und den Kolben f zurückdrängen, womit der Farbzufluß geöffnet wird. Bei der Absperrbewegung für die Preßluft wird umgekehrt zuerst der Kolben f entlastet und der Flüssigkeitszufluß abgesperrt, dann erst die Preßluftzuleitung ganz geschlossen.the compressed air also flows through the channels i, y, 2 and ζ into the cylinder g and pushes back the piston f , which opens the flow of paint. Conversely, during the shut-off movement for the compressed air, piston f is first relieved and the flow of liquid shut off, and only then is the compressed air feed completely closed.
