Description

Die Erfindung betrifft einen Gasbrenner, vorzugsweise Verdampfungsölbrenner, bestehend aus einem mit einer Zuführung für gasförmigen Brennstoff versehenen, eine Innenbohrung mit einem Innengewinde aufweisenden Sockel, aus einem eine Düsenöffnung enthaltenden zylindrischen Düsenkörper mit einem in den Sockel einschraubbaren Aus­sengewinde und aus einem dem Düsenkörper zugeordneten Sieb.The invention relates to a gas burner, preferably an evaporating oil burner, consisting of a base provided with a feed for gaseous fuel, an inner bore with an internal thread, a cylindrical nozzle body containing a nozzle opening with an external thread that can be screwed into the base, and a sieve assigned to the nozzle body.

In der Praxis besteht der Brenner aus dem Düsenkörper und einem gesonderten Sieb. Bei einer Verstopfung muß der Düsenkörper aus dem Sockel herausgeschraubt, das Sieb herausgenommen und beides gereinigt werden, worauf beide Teile wieder in den Sockel eingesetzt und der Düsenkörper festgeschraubt werden muß. Das Reiningen des Brenners ist somit sehr zeitaufwendig.In practice, the burner consists of the nozzle body and a separate sieve. In the event of a blockage, the nozzle body must be unscrewed from the base, the sieve removed and both cleaned, whereupon both parts must be replaced in the base and the nozzle body must be screwed tight. Cleaning the burner is therefore very time-consuming.

Der Erfindung liegt die Aufgabe zugrunde, einen Brenner der eingangs genannten Art zu schaffen, der eine einfache und zeitsparende Kontrolle und Reinigung von Düsenkörper und Sieb ermöglicht.The invention has for its object to provide a burner of the type mentioned, which enables simple and time-saving control and cleaning of the nozzle body and sieve.

Dies wird erfindungsgemäß dadurch erreicht, daß der Düsen­körper mit einem verlängerten Schaft versehen ist, der in seiner ganzen Länge von einer der Düsenöffnung vorge­schalteten Längsbohrung durchsetzt ist, daß der Schaft innerhalb eines vorbestimmten Bereiches mit einer Mehr­zahl von in die Längsbohrung mündenden radialen Bohrungen versehen ist, deren Durchmesser kleiner ist als der Durch­messer der Düsenöffnung, wobei die Summe der Querschnitte aller Bohrungen größer ist, vorzugsweise wesentlich grös­ser ist, als der Querschnitt der Düsenöffnung, und daß in dem die radialen Bohrungen enthaltenden Bereich des Schaftes ein mit der Brennstoffzuführung in Verbindung stehender Ringkanal vorgesehen ist.This is achieved according to the invention in that the nozzle body is provided with an elongated shaft which is penetrated in its entire length by a longitudinal bore connected upstream of the nozzle opening, in that the shaft is provided within a predetermined range with a plurality of radial bores opening into the longitudinal bore, the diameter of which is smaller than the diameter of the nozzle opening, the sum of the cross sections of all the bores being larger, preferably being substantially larger than the cross section of the nozzle opening, and that In the region of the shaft containing the radial bores, an annular channel connected to the fuel supply is provided.

Düsenkörper und Sieb bestehen hier also aus einem Stück, das eine leichte und zeitsparende Handhabung, Inspektion und Reinigung ermöglicht.The nozzle body and sieve are made of one piece, which enables easy and time-saving handling, inspection and cleaning.

Die Erfindung ist im folgenden anhand der Zeichnung an einem Ausführungsbeispiel näher erläutert.The invention is explained below with reference to the drawing using an exemplary embodiment.

Der Brenner besteht im wesentlichen aus einem Sockel 10 und einem Düsenkörper 16.The burner essentially consists of a base 10 and a nozzle body 16.

Der Sockel 10 enthält eine Innenbohrung 11, die in dem dem Boden zugewandten Bereich mit einem Innengewinde 12 versehen ist. An dem Sockel ist eine Brennstoffzuführung 13 angeschlossen.The base 10 contains an inner bore 11 which is provided with an internal thread 12 in the area facing the floor. A fuel feed 13 is connected to the base.

Der Sockel 10 nimmt einen allgemein mit 14 bezeichneten Düsen­körper auf, der aus einem Kopfteil 15 und einem Schaftteil 16 besteht. Der Schaftteil 16 trägt an seinem freien Ende ein Außengewinde 18, welches in das Innengewinde 12 des Sockels einschraubbar ist.The base 10 receives a nozzle body, generally designated 14, which consists of a head part 15 and a shaft part 16. The shaft part 16 carries at its free end an external thread 18 which can be screwed into the internal thread 12 of the base.

Der Düsenkörper 14 enthält in seinem Kopfteil 15 eine Düsen­öffnung 17, an die sich eine Bohrung 20 mit größerem Durch­messer anschließt, die den gesamten Düsenkörper durchsetzt und am freien Ende des Schaftteiles 16 mündet.The nozzle body 14 contains in its head part 15 a nozzle opening 17, which is followed by a bore 20 with a larger diameter, which penetrates the entire nozzle body and opens at the free end of the shaft part 16.

In einem Bereich zwischen Kopfteil und Außengewinde 18 ist der Schaftteil 16 mit radialen Bohrungen 19 versehen, die innen in die Bohrung 20 münden. Diese radialen Bohrungen haben zweckmäßig einen geringeren Durchmesser als die Düsen­öffnung 17, besitzen aber insgesamt einen Querschnitt, der größer ist, vorzugsweise erheblich größer ist, als der Quer­schnitt der Düsenöffnung 17.In an area between the head part and the external thread 18, the shaft part 16 is provided with radial bores 19 which open into the bore 20 on the inside. These radial bores advantageously have a smaller diameter than the nozzle opening 17, but overall have a cross section which is larger, preferably considerably larger, than the cross section of the nozzle opening 17.

Im Bereich der radialen Bohrungen 19 ist der Schaft 16 mit einer Ringnut versehen, durch die ein Ringkanal 21 gebildet wird, durch den der durch die Brennstoffleitung 18 zuge­führte gasförmige Brennstoff in die radialen Bohrungen 19 und somit in die zentrale Bohrung 20 des Düsenkörpers 14 gelangen kann.In the region of the radial bores 19, the shaft 16 is provided with an annular groove, through which an annular channel 21 is formed, through which the gaseous fuel supplied through the fuel line 18 can get into the radial bores 19 and thus into the central bore 20 of the nozzle body 14 .

Natürlich kann der Ringkanal (21) auch durch eine Ringnut in der Innenwand des Sockels 10 gebildet werden, oder es können sowohl im Düsenkörper (14) als auch im Sockel einen gemeinsamen Ringkanal bildende Ringnuten vorgesehen sein.Of course, the ring channel (21) can also be formed by an annular groove in the inner wall of the base 10, or ring grooves forming a common ring channel can be provided both in the nozzle body (14) and in the base.

Durch die besondere Ausbildung des Düsenkörpers sind Düsen­öffnungen und Sieb in dem einteiligen Düsenkörper enthalten, so daß die Handhabung bei einer Reinigung und Inspektion einfach ist, wobei auch die Düsenöffnung von zwei Seiten her zugänglich ist und sie somit visuell einfach geprüft werden kann.Due to the special design of the nozzle body, nozzle openings and sieve are contained in the one-piece nozzle body, so that handling during cleaning and inspection is simple, the nozzle opening being accessible from two sides and thus being easy to inspect visually.
