Uppfinnare: II. C. Hebard. Inventor: II. C. Hebard.

Foreliggande uppfinning Miff& sig till en for flytande bransle, exempelvis olja eller sprit, avsedd brannare f5r lampor, spisar, kaminer och dylikt av det slag, vid vilket det flytande branslet matas fran en branslebehallare genom en forgasare, som under driften uppvarmes genom brannaren eller genom en av brannaren uppburen mantel. Vid brannareanordningar av ifragavarande slag fir det av vikt, att anordningar, sasom rensnalar eller dylikt, finnas for rensning av brannarens munstycke, som maste ha liten diameter och darfor visar benagenhet att tilltappas av kolavsattningar eller andra frammande partiklar. Dylika rensanardningar aro mera effektiva, om de aro placerade inuti forgasaren an om de bringas att verka utifran, emedan alla hindrande frammande partiklar i forstnamnda fall avlagsnas fran munstycks5ppningen i gasstrommens riktning i stallet for i motsatt riktning. The present invention relates to a burner for liquid fuels, for example oil or spirits, intended for burners for lamps, stoves, stoves and the like of the kind in which the liquid fuel is fed from a fuel tank through a carburettor, which during operation is heated by the burner or by a mantle carried by the burner. In the case of burner devices of the type in question, it is important that devices, such as cleaning needles or the like, are provided for cleaning the burner nozzle, which must have a small diameter and therefore show a tendency to be drained by carbon deposits or other foreign particles. Such cleaning devices are more effective if they are placed inside the carburettor than if they are made to act from the outside, since all obstructing foreign particles in the former case are removed from the nozzle opening in the direction of the gas stream in the opposite direction.

Tidigare anvanda anordningar Ea- rensning av munstyeket vid forgasningsbrannare inifran fungera pa sã satt, att rensnalen inuti forgasaren hojes mot munstycket. En svarighet harvicllag utgor mojligheten for tryeklackage vid det stalle, dar manovreringsmekanismen är inford i branslebehallaren. Man har foreslagit organ, genom vilka detta lockage sakert forhindras, men aven bortsett harifran varo ,dylika rensanordningar tamligen komplicerade. Previously used devices The cleaning of the nozzle in gasification burners from the inside works in such a way that the cleaning needle inside the carburettor is raised towards the nozzle. A responsible harvicllag constitutes the possibility of pressure leakage at the stable, where the maneuvering mechanism is introduced in the fuel tank. Means have been proposed by which this locking is securely prevented, but even apart from this, such cleaning devices are rather complicated.

Uppfinningen har till andamal att astadkomma en forbattrad och enklare anordning for rensning av en fOrgasarbrannares munstycke inifran, som icke är behaftad med nyssnamnda olagenhet och som icke nodvandiggor anvandning av driftstrycket motstaende packboxar. The object of the invention is to provide an improved and simpler device for cleaning the nozzle of a carburettor burner from the inside, which is not encumbered with the aforementioned malfunction and which does not necessarily require the use of the operating pressure-resistant stuffing boxes.

Brannare enligt uppfinningen är kfinnetecknad darav, att en for rensning av bran- narens munstycksoppning avsedd rensnal, som uppbares ,eller overgar i ett i forhallande till en branslebehallare fixt organ är anord- nad inuti ett forgasareror, som ãr ef tergivhart fOrbundet med branslebehallaren, sa att .det kan nedpressas, i andamal aft rensnalenma intrada i brannarens munstycksoppning. Burners according to the invention are characterized in that a cleaning needle intended for cleaning the nozzle opening of the burner, which is carried, or passes into a means fixed in relation to a fuel tank, is arranged inside a carburettor tube, which is connected to the fuel tank. that .it can be depressed, in andamal aft rensnalenma intrada in the burner nozzle opening.

Enligt ett sarskilt kanneteeken for uppfinningen utgores det rensnalens uppbarande fixa organet av en stang, vars nedre finde fir fast inuti brfinslebehallaren, Over vilken bran-- naren as anordnad, varjamte forgasarroret uppbar brannarens munstycke vid sin ovre ande och en manovrerin.gsanordning finnes, medelst vilken namnda forgasarror med munstycket kan forskjutas i axiell riktning, varvid en bojlig metallbalgsanordning fOrenar namnda fOrgasarror med behallaren saint fungerar sasom returfjader ef ter att roret har tryckts ned for att rensa brannaremunstyckets oppning. According to a special feature of the invention, the support means for fixing the cleaning needle consists of a rod, the lower fin of which is fixed inside the fuel container, above which the burner is arranged, and the carburettor tube carries the burner nozzle at its upper end and a maneuvering device is present. which said carburettor with the nozzle can be displaced in the axial direction, wherein a flexible metal bellows device removes said carburettor with the container saint acts as a return spring after the pipe has been pressed down to clean the opening of the burner nozzle.
