Claims (1)

Luftschaumerzeuger Zusatz zum Zusatzpatent 666 5@5 Die Erfindung betrifft eine weitere Ausbildung des für Feuerlöschzwecke bestimmten Luftschaumerzeugers nach Patent 666 5I5 mit zwei oder mehr gegen die Mittelachse des Schaumrohres geneigten Düsen zur Zuführung der schaumbildenden Flüssigkeit oder von Wasser und Schaumbildner. Air foam generator Addendum to additional patent 666 5 @ 5 The invention relates to a further development of the air foam generator intended for fire extinguishing purposes according to patent 666 5I5 with two or more inclined towards the central axis of the foam tube Nozzles for feeding the foaming liquid or water and foaming agent. Bei dem Luftschaumerzeuger nach dem Patent 666 515 erfolgt die Zerstäubung der schaumbildenden Flüssigkeit durch zwei oder mehr, vorzugrsweise drei Düsen welche gegen. einander und gegen die Mittelachse des Schaumrohres geneigt derart angeordnet sind, daß die aus den Düsen austretenden Flüssigkeitsstrahlen sich in einem Punkt treffen und so die Flüssigkeit durch Aufeinanderprallen zerstäubt wird. In the case of the air foam generator according to patent 666 515, atomization takes place the foam-forming liquid through two or more, preferably three, nozzles against. so arranged inclined to one another and to the central axis of the foam tube are that the jets of liquid emerging from the nozzles are at one point hit and so the liquid is atomized by colliding with each other. Da die Leistung eines derartigen Schaumerzeugers sowohl hinsichtlich der Beschaffenheit des erzeugten Schaumes als auch hinsichtlich der Tragweite des Schaumstrahles bei sonst gleichen Verhältnissen erheblich verbessert werden kann, wenn die Auslässe der gegeneinander geneigten Düsen so nahe aneinander angeordnet sind, daß die aus den D üsenauslässen austretenden Strahlen unmittelbar an den Düsenauslässen oder kurz hinter denselben gegeneinandertreffen, so sind zur Erzielung dieser Wirkung bei dem Luftschaumerzeuger gemäß der Erfindung die Düsenmündungen bis nahe an die Mittelachse des Düsenkopfes zusammengerückt, so daß sich die Strahlen unmittelbar an oder nahe an den Mündungen treffen. Auch kann bei einem solchen Luftschaumerzeuger der Düsenkopf aus einem Stück bestehen. das die Strahldüsen bildende Bohrungen aufweist. Since the performance of such a foam generator in terms of both the nature of the foam produced as well as the scope of the The foam jet can be significantly improved with otherwise the same conditions, when the outlets of the inclined nozzles are so close to each other are that the jets emerging from the nozzle outlets are directly at the nozzle outlets or meet shortly after them, so are to achieve this effect in the air foam generator according to the invention, the nozzle mouths to close to the Center axis of the nozzle head moved together so that the jets are immediately meet at or near the mouths. Such an air foam generator can also the nozzle head consist of one piece. which has bores forming the jet nozzles. Bei der neuen Ausbildung des Luftschaumerzeugers wird außer dem Vorteil einer besseren Schaumausbildung zugleich der Vorteil einer wesentlich einfacheren und leichteren Bauart des Schaumerzeugers erreicht. The new design of the air foam generator also has the advantage a better foam formation at the same time the advantage of a much simpler one and a lighter design of the foam generator. In der Zeichnung ist ein Ausführungsbei spiel des neuen Luftschaumerzeugers dargestellt, und zwar zeigt Abb. 1 den unteren Teil eines als Strahlrohr ausgebildeten Schaumerzeugers, teilweise im Schnitt, Abb. 2 den Schnumerzeuger im Schnitt nach der Linie 11-11 der Abb. 1 und Abb. 3 das Schaumstrahlrohr nach Abb. in einem kleineren Maßstabe. In the drawing, a Ausführungsbei is game of the new air foam generator shown, namely Fig. 1 shows the lower part of a designed as a jet pipe Foam generator, partially in section, Fig. 2 shows the sniffer generator in section the line 11-11 of Fig. 1 and Fig. 3 the foam jet pipe according to Fig. in a smaller one Scale. In dem Schaumrohr 1 befindet sich am Eingangsende der Düsenkopf 2, dessen Düsen durch die schräg gegeneinandergerichteten Bohrungen 3 gebildet sind, deren Auslässe kurz vor dem Austritt aus dem Kopf 2 teilweise ineinander übergehen (Abb. 2) so daß die Strahlen der schaumbildenden Flüssigkeit sogleich nach ihrem Austritt aus den Düsen 3 aufeinanderprallen und die Flüssigkeit dadurch zerstäubt wird. Für den Zutritt der zur Schaumbildung erforderlichen Luft sind im Mantel des Rohres in Höhe des Düsenkopfes 2 mehrere Öffnungen ß vorgesehen. The nozzle head 2 is located in the foam tube 1 at the inlet end, the nozzles of which are formed by the bores 3 facing each other at an angle, the outlets of which partially merge into one another shortly before exiting the head 2 (Fig. 2) so that the jets of the foam-forming liquid immediately follow their Exit from the nozzles 3 collide and the liquid is atomized as a result will. For the access of the air required for foam formation are in the jacket of the Tube provided several openings ß at the level of the nozzle head 2. PATENTANSPRÜCIIE: 1. Luftschaumerzeuger für Feuerlöschzwecke nach Patent 666 515 mit zwei oder mehr gegen die Mittelachse des Schaumrohres geneigten Düsen zur Zuführung der schaumbildenden Flüssigkeit oder von Wasser und Schaumbildner, dadurch ge kennzeichnet. daß die Düsenmündungen bis nahe an die Mittelachse des Düsenkopfes (2) zusammengerückt sind, so daß sich die Strahlen unmittelbar an oder nahe an den Mündungen treffen. PATENT CLAIM: 1. Air foam generator for fire extinguishing purposes according to Patent 666 515 with two or more inclined towards the central axis of the foam tube Nozzles for supplying the foaming liquid or water and foaming agent, characterized. that the nozzle orifices close to the central axis of the Nozzle head (2) are moved together so that the jets are directly on or meet close to the mouths.
