  Zusatzpatent zum Hauptpatent     Nr.    303445  Regulierbarer Gasbrenner mit mehreren sukzessive zueinander parallel     sehaftbaren          Gasaustrittsdüsen       Gegenstand vorliegender Erfindung ist  <B>cl</B>       (,in        regullerbarer    Gasbrenner gemäss dem     Pa-          tentansprueb.    des Hauptpatentes, also ein  solcher mit mehreren sukzessive zueinander  parallel schaltbaren     Gasaustrittsdüsen,    wobei       der    Speisung ein und desselben Mischrohres       iiiindestens    zwei     nebeneinanderliegende    Düsen  dienen.  



       Ini        Ausführun,#sbeispiel    des Hauptpatentes  führen, vom     Hahngehäuse    ausgehend,     Speise-          leitLingen        züi    den     nebeneinanderliegenden     Düsen. Im Gegensatz dazu ist der Gasbrenner  gemäss der vorliegenden Erfindung dadurch       gekennzeiehnet,        dass    die Düsen durch im       Haliii-ehäuse    selbst vorgesehene Bohrungen  ,gebildet sind.

   Das erlaubt zum Beispiel, die       0-          ,leiehen        Hahngehäuse    zu verwenden, wie sie  bisher bei einer einzigen Düse, also mit, einer       einzi,-en        Bohruing    gebraucht wurden.  



  Beiliegende Zeichnung zeigt eine     beispielg-          weise    Ausführungsform des Erfindungsgegen  standes. Darin ist       Fig.   <B>1</B> ein schematischer Schnitt senkrecht  Zn       zur    Achse des     Hahnkükens,    mit Kükenstellung  <B>für</B> Grossfeuer,       Fig.   <B>9-</B> ein der     Fig.   <B>1</B> entsprechender  Schnitt mit Kükenstellung für Kleinfeuer und       Fi-.   <B>3</B> ein     Grundriss    des Hahnes.  



  Die     Gaszufuhrleitung   <B>1</B> mündet in die  Bohrung 2 des     Hahngehäuses   <B>3,</B> in welchem  das Küken 4 mit, der     Bohrun,-   <B>5</B> drehbar ge  lagert ist. Oberhalb des Kükens 4 hat das    Gehäuse<B>3</B> zwei Bohrungen<B>6</B> gleichen Durch  messers, deren äusseres Ende     nebeneinander-          liegende        Gasaustrittsdüsen    bilden, die beide in  das gleiche Mischrohr<B>7</B> blasen.  



  Im gezeigten Beispiel ist ein gleiches       Halingehäuse    verwendet wie in Brennern mit       nur    einer Bohrung, mit dem Unterschied,     dass     an Stelle der einen Bohrung deren zwei vor  gesehen sind. Man könnte auch mehr als zwei  Bohrungen<B>6,</B> das heisst mehr als zwei Düsen  pro Hahn und Mischrohr vorsehen.  



  In der Stellung des Kükens gemäss     Fig.   <B>1</B>  werden beide Bohrungen<B>6,</B> also beide Düsen       gespiesen.    Es ist dies die Stellung für Gross  feuer, das heisst für maximale Gasmenge. Die  beiden     Düsenaustrittsquersehnitte    sind zusam  men kleiner als der Querschnitt der Bohrung  im Küken und als der Querschnitt der     Zu-          leituno,   <B>1.</B> Es tritt in den beiden Düsen die  maximale Austrittsgeschwindigkeit     auf.     



  Dreht man das Küken aus der Stellung  der     Fig.   <B>1</B> in diejenige der     Fig.    2, so kann  das Gas durch die Bohrung<B>5</B> nur in die linke  Bohrung<B>6</B> der     Fig.    2 strömen, während die  rechte Bohrung<B>6</B> von der Gaszufuhr abge  schlossen ist. In dieser Regulierstellung ge  mäss     Fig.    2 herrscht in der linken Düse wieder  die maximale     GasgeschwindIgkeit,    da das  Küken keine Drosselwirkung ausübt. In den       Zwisehenstellungen    wird der Brenner durch  die Drosselwirkung des Kükens reguliert, wo  bei in der abzuschaltenden Düse nicht mehr      die maximale     Gesehwindigkeit    herrscht.

   Da  aber die Drosselung immer nur in der     abzu-          sehaltenden    Düse, erfolgt, wird ihr     Einfluss     kaum bemerkbar.



  Additional patent to the main patent no. 303445 Adjustable gas burner with several successively adhering gas outlet nozzles parallel to one another The subject of the present invention is <B> cl </B> (, in adjustable gas burner according to the patent claim. Of the main patent, so one with several successively parallel switchable Gas outlet nozzles, with at least two juxtaposed nozzles serving to feed one and the same mixing tube.



       In the execution example of the main patent, starting from the tap housing, feed guides lead to the adjacent nozzles. In contrast to this, the gas burner according to the present invention is characterized in that the nozzles are formed by bores provided in the halide housing itself.

   This allows, for example, to use the borrowed tap housing, as it was previously used with a single nozzle, i.e. with a single boring.



  The accompanying drawing shows an exemplary embodiment of the subject matter of the invention. FIG. 1 is a schematic section perpendicular Zn to the axis of the cock plug, with the plug position for a large fire, FIG. 9 - one of the figures B> 1 </B> corresponding cut with chick position for small fire and fi. <B> 3 </B> a floor plan of the cock.



  The gas supply line <B> 1 </B> opens into the bore 2 of the tap housing <B> 3 </B> in which the plug 4 is rotatably supported with the bore - <B> 5 </B>. Above the plug 4, the housing <B> 3 </B> has two bores <B> 6 </B> of the same diameter, the outer ends of which form gas outlet nozzles lying next to one another, both of which into the same mixing tube <B> 7 </ B> blow.



  In the example shown, the same Haline housing is used as in burners with only one bore, with the difference that two are seen in place of one bore. It would also be possible to provide more than two bores <B> 6 </B> that is to say more than two nozzles per tap and mixing tube.



  In the position of the plug according to FIG. 1, both bores 6, that is, both nozzles, are fed. This is the position for large fires, i.e. for maximum gas volume. The two cross sections of the nozzle outlet are together smaller than the cross section of the bore in the plug and than the cross section of the inlet, <B> 1. </B> The maximum exit speed occurs in the two nozzles.



  If the plug is rotated from the position of FIG. 1 to that of FIG. 2, the gas can only pass through the bore <B> 5 </B> into the left bore <B> 6 < / B> of Fig. 2 flow while the right hole <B> 6 </B> is closed abge from the gas supply. In this regulating position according to FIG. 2, the maximum gas speed again prevails in the left nozzle, since the plug does not exert any throttling effect. In the intermediate positions, the burner is regulated by the throttle effect of the plug, where the maximum speed no longer prevails in the nozzle to be switched off.

   However, since the throttling only takes place in the nozzle to be blocked, its influence is hardly noticeable.
