Es sind bereits Gasfernzünder bekannt, bei welchen die Zündpille im Brennerkopf verschiebbar gelagert ist, so daß sie zwecks Zündung in den Bereich des Gasstromes und danach wieder in die geschützte Lage im Brennerkopf gebracht werden kann. Bei diesen Gasfernzündern ist die Zündpille zwar vor der unmittelbaren Einwirkung der Flamme geschützt, sie steht aber doch noch unter derGas remote igniters are already known in which the igniter can be displaced in the burner head is stored so that it is for the purpose of ignition in the area of the gas flow and then back in the protected position in Burner head can be brought. With these remote gas detonators, the detonator is indeed Protected from the immediate effect of the flame, but it is still under the

ίο Einwirkung der strahlenden Hitze.ίο exposure to radiant heat.

Um auch diese Einwirkung zu vermeiden, ist das Zündmittel der Erfindung* gemäß in einem seitlich gelochten, dachartig abgeschlossenen Gehäuse gelagert, welches mit der Pille verschoben wird. Da das Zündmittel im Innern dieses Gehäuses angebracht ist, würde der durch den Gasstrom hervorgerufene Luftzug nicht genügen, um das. zur Entzündung nötige Gasluftgemisch in der Nähe des Zündmittels hervorzubringen. Zu diesem Zwecke muß deshalb eine Vorrichtung zur künstlichen Luftzuführung vorhanden sein, die gegebenenfalls auch regelbar sein kann, so daß durch entsprechende Einstellung derselben das für die Zündung günstigste Mischungsverhältnis erzielbar ist.In order to avoid this effect as well, the ignition means of the invention is * according to in a laterally perforated, roof-like closed housing mounted, which with the Pill is postponed. Since the ignition device is located inside this housing, the draft caused by the gas flow would not be sufficient to cause ignition to produce the necessary gas-air mixture in the vicinity of the ignition means. For this purpose, a device must therefore Artificial air supply is available, which can also be regulated if necessary, so that the most favorable mixing ratio for ignition can be achieved by setting the same accordingly is achievable.

In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt, und zwar zeigt:In the drawing, two exemplary embodiments of the subject matter of the invention are shown, namely shows:

Fig. i einen Längsschnitt durch den unteren Teil des Brenners, währendFig. I is a longitudinal section through the lower part of the burner, while

Fig. 2 den ganzen Brenner in einem zum ersten senkrechten Längsschnitt zeigt.Fig. 2 shows the entire burner in a longitudinal section perpendicular to the first.

Fig. 3 veranschaulicht den oberen Teil des Brenners bei einer anderen Stellung der Teile.Fig. 3 illustrates the upper part of the burner with the parts in a different position.

Fig. 4 ist ein Schnitt durch einen Druckluftzylinder. Fig. 4 is a section through an air cylinder.

Fig. 5' ist ein Längsschnitt durch eine andere Ausführungsform des Brenners.Fig. 5 'is a longitudinal section through another embodiment of the burner.

Bei der in den Fig. 1 bis 4 dargestellten Ausführungsform ist das die Zündpille enthaltende Gehäuse a, welches in einem zylindrischen Teil b des Brennerkopfes verschiebbar ist, mit seitlichen öffnungen c versehen und oben durch eine dachartige Kappe d abgeschlossen, die sich mit ihrem Rand auf den kegelstutzförmigen Ansatz e des sonst in bekannter Weise ausgeführten .Brennerkopfes aufsetzt und dadurch den die Zündpille enthaltenden Raum nach außen hin ab- schließt. Das Anheben des Zündpillengehäuses erfolgt unter Zuhilfenahme einer Druckluftvorrichtung, wie sie bei Gasfernzündem. bekannt sind. Im besonderen ist die Ei|irichtung so getroffen, daß das Gehäuse a mit Hilfe einer Stange/ angehoben wird, die mittels eines von der Stange / des Druckluftzylinders g beeinflußten Schiebers h gehoben werden kann. Der Druckluftzylinder g steht mit dem in Fig. 4 dargestellten Zylinder i in '60 Verbindung, dessen unter Federdruck stehender Kolben j von Hand in den Zylinder hineingedrückt werden kann, um die darin befindliche Luft zu verdichten. Die so verdichtete Luft tritt durch die Verbindungsleitung k unter den Kolben des Druckluftzylinders g und bewirkt mittels der Stange / das Anheben des Gehäuses α und mit Hilfe der an der Stange befestigten Schaltklinke m das Verdrehen des mit einem Schaltrad η ηο In the embodiment shown in FIGS. 1 to 4, the housing a containing the squib, which is displaceable in a cylindrical part b of the burner head , is provided with lateral openings c and is closed at the top by a roof-like cap d, which extends with its edge the cone-shaped extension e of the burner head, which is otherwise designed in a known manner, and thereby closes off the space containing the squib from the outside. The primer housing is lifted with the aid of a compressed air device, as is the case with remote gas igniters. are known. In particular, the direction of rotation is such that the housing a is raised with the aid of a rod / which can be raised by means of a slide h influenced by the rod / the compressed air cylinder g . The compressed air cylinder g is connected to the cylinder i shown in FIG. 4, whose piston j , which is under spring pressure, can be pushed into the cylinder by hand in order to compress the air contained therein. The air compressed in this way passes through the connecting line k under the piston of the compressed air cylinder g and by means of the rod / the lifting of the housing α and with the help of the pawl m attached to the rod causes the rotation of the with a ratchet wheel η ηο

Claims

equipped gas tap so that ignition can take place. After the air pressure in the pressure cylinder g has ceased, the housing a lowers and returns to its initial position, whereby the primer comes out of the area of the flame. In order to achieve the most favorable mixing ratio of gas and air for ignition at the ignition point, special channels have already been built into the burner head in order to supply air to the igniter. However, this device is not sufficient in the present case, because the formation of a sufficiently strong air flow is made more difficult by the cover of the squib housing. An air supply pipe o (Fig. 2) is therefore provided, which branches off from the working cylinder g and is guided on the side of the burner mixing pipe up to the level of the ignition point, to which it supplies air when the igniter is used. This tube is dimensioned so that it just allows the necessary amount of air to reach the ignition point; however, it can also have a flow cross-section which can optionally be regulated by an adjusting screw and which can be adjusted to the amount of air required to produce the correct mixing ratio. Since the squib must be replaced from time to time, it is desirable to make the housing α accessible without having to destroy the mantle when it is lifted from the burner head. For this purpose, the device described is modified in the manner shown in FIG. In this case, the cap d has no protruding edge and the cylindrical part b has no bearing surface, so that the housing a can not only be pushed upwards out of the burner head, but also allows the entire burner head to be lifted off without being carried along by it. In order to prevent the housing α from falling down after the burner head has been lifted off, the rod f is firmly connected to the slide h. The housing α thus remains seated on the lower part of the burner so that the squib can be easily replaced. Pat ε ν τ-Α ν Proverbs:
