    Rückschlagsicherungs-Vorrichtung für Schweissbrenner.   



   Vorliegende Erfindung besteht in einer Rückschlagsicherungsvorrichtung für   Schweiss-   brenner, welche fähig ist, die Fortpflanzung der Explosion mit Sicherheit zu   verhüten.   Dieses System gründet sich auf der Eigenschaft von Rohrleitungen geringen Querschnitts, die Fortpflanzug einer Explosion von Gasgemischen, infolge der   Kühlwirkung,   welche die Wände auf 
 EMI1.1 
 Sauerstoff enthalten, können nur Leitungen von sehr kleinem Querschnitt oder capillarleitungen. deren Öffnungen nur einige Zehntel Millimeter betragen, die Explosion aufhalten. Handelt es sich aber um ein Gemisch von Acetylen und Sauerstoff, so muss der Durchmesser der Öffnungen noch kleiner sein als zwei Zehntel Millimeter. 



   Auf der Zeichnung sind einige   Ausführungsforrnen beispielsweist dargestellt, und zwar     zeigt : Fig. l   eine Draufsicht auf eine Sicherungsvorrichtung, welche aus mehreren nebeneinanderliegenden Teilen besteht ; Fig. 2 veranschaulicht einen Schnitt nach der Linie A-B der Fig. 1,

   Das Anbringen der Cappillarschlitze in den Diaphragmen gewisser Dicke bietet jedoch Schwierigkeiten. Die praktischeste Durchführung der Erfindung besteht nun darin, dass man das Diaphragma in einzelne, mit Vorsprüngen oder Warzen verschene Elemente zerlegt,

PATENT-ANSPRÜCHE :
1. Rückschlagsicherungs-Vorrichtung für Schweissbrenner, bestehend in Kapillarschlitzen (f) von   grosser Kühlfläche,   welche durch den Zusammenbau einzelner, mit Vorsprüngen (h) geringer Stärke ausgestatteter   Elfemente (. g) gebildet   sind.

    Kickback protection device for welding torches.



   The present invention resides in a flashback device for welding torches which is capable of reliably preventing the propagation of the explosion. This system is based on the property of pipelines of small cross-section, the propagation of an explosion of gas mixtures, due to the cooling effect which the walls on
 EMI1.1
 Only pipes with a very small cross-section or capillary pipes can contain oxygen. whose openings are only a few tenths of a millimeter, which stop the explosion. If, however, it is a mixture of acetylene and oxygen, the diameter of the openings must be smaller than two tenths of a millimeter.



   Some embodiments are shown by way of example in the drawing, namely: FIG. 1 shows a plan view of a safety device, which consists of several parts lying next to one another; Fig. 2 illustrates a section along the line A-B of Fig. 1,
 EMI1.2
 



   However, making the capillary slots in the diaphragms of a certain thickness presents difficulties. The most practical implementation of the invention consists in dividing the diaphragm into individual elements with projections or warts,
 EMI1.3
 to be arranged in the mixing chamber, and the device according to FIG. 1 is particularly suitable for this purpose. and 4.
