Description

Die Erfindung betrifft einen Feuerlöscher mit unter Druck stehendem Löschmittel. Bei derartigen Feuerlöschern ist es bereits bekannt, die den Austreibdruck liefernde Druckluft getrennt von dem Löschmittel in einem im Löschmittelbehälter angeordneten Behälter unterzubringen, der sich beim Öffnen des Auslaßventils des Löschmittelbehälters unter dem Druck der eingeschlossenen Luft ausdehnt und das Löschmittel austreibt. Gegenüber einem Feuerlöscher dieser Art besteht die, Erfindung darin, daß der Behälter für die Druckluft aus einem Wellrohrbehälter besteht, dessen Seitenwandung entweder aus einem ein Stück bildenden Wellrohr oder aus mehreren teleskopartig ineinandergeführten Wellrohren besteht.The invention relates to a pressurized fire extinguisher Extinguishing agent. In such fire extinguishers, it is already known that the expulsion pressure Delivering compressed air separated from the extinguishing agent in one in the extinguishing agent container to accommodate arranged container, which is when opening the outlet valve of the Extinguishing agent container expands under the pressure of the enclosed air and that Expels extinguishing agent. Compared to a fire extinguisher of this type, there is the invention is that the container for the compressed air consists of a corrugated pipe container, the Side wall either from a corrugated pipe forming one piece or from several consists of telescopically nested corrugated pipes.

In der Zeichnung ist ein Ausführungsbeispiel des Feuerlöschers nach der Erfindung dargestellt.In the drawing, an embodiment of the fire extinguisher is according to of the invention shown.

a ist der Löschmittelbehälter, der oben durch den Deckel b und unten durch den Boden i abgeschlossen ist. Am Deckel b ist der Löschmittelauslaß b1 angeordnet, der über das nicht dargestellte Auslaßven:til zur Ausspritzdüse führt. Im Behälter a sind die Wellrohre r und s teleskopartig ineinandergeführt angeordnet, von denen das äußere Wellrohr r durch den Deckel r1 abgeschlossen ist. Das Ende des Wellrohres s ist durch eine zylindrische Büchse o mit dem unteren Ende des äußeren Wellrahres r dicht schließend verbunden und am Boden i befestigt. Am Boden i ist ferner das Einfüllventil n für die Druckluft angebracht. Die Wellrohre r und s in Verbindung mit dem Deckel r1 und einem Teil des Bodens i begrenzen den Raum für die Druckluft, während der restliche Teil des Behälters a mit dem flüssigen oder pulverförmigen Löschmittel gefüllt ist.a is the extinguishing agent container, which is closed at the top by the cover b and at the bottom by the bottom i . The extinguishing agent outlet b1 is arranged on the cover b and leads to the injection nozzle via the outlet valve (not shown). In the container a, the corrugated pipes r and s are arranged telescopically one inside the other, of which the outer corrugated pipe r is closed by the cover r1. The end of the corrugated pipe s is tightly connected by a cylindrical sleeve o with the lower end of the outer corrugated pipe r and attached to the bottom i. The filling valve n for the compressed air is also attached to the bottom i. The corrugated pipes r and s in connection with the cover r1 and part of the bottom i limit the space for the compressed air, while the remaining part of the container a is filled with the liquid or powdery extinguishing agent.

Die Wirkungsweise ist derart, daß beim Öffnen des Auslaßventils des Löschmittelbehälters a sich die in dem Wellrohrbehälter s, r, r1 eingeschlossene Druckluft entspannt und dabei das Wellrohr r mit Deckel r1 nach oben treibt, wodurch das Löschmittel unter Druck ausgespritzt wird. Die Gebrauchslage des Feuerlöschers spielt dabei keine Rolle.The operation is such that when you open the exhaust valve of the Extinguishing agent container a is enclosed in the corrugated pipe container s, r, r1 Compressed air relaxes and thereby drives the corrugated pipe r with cover r1 upwards, whereby the extinguishing agent is sprayed out under pressure. The position of use of the fire extinguisher does not matter.
