Description

Die vorliegende Erfindung betrifft eine Gaszufuhreinrichtung für einen Gasbrenner mit einer Abdeckeinrichtung zum Abdecken einer radialen Öffnung in einer Gaszufuhrleitung für einen Gasbrenner und eine Kochstelle. Um eine vollständige Gasverbrennung zu erreichen, wird in eine Gaszufuhrleitung eines Gasbrenners Primärluft eingespeist. Hierzu kann an der Gaszufuhrleitung eine radiale Öffnung vorgesehen sein. Je nach dem verwendeten Gas, wie beispielsweise Propangas oder Stadtgas ist ein unterschiedlicher Volumenstrom an Primärluft erforderlich. Damit der Gasbrenner für verschiedene Gasarten einsetzbar ist, ist eine Querschnittsfläche der radialen Öffnung einstellbar. Hierzu kann die radiale Öffnung entsprechend der erforderlichen Menge an Primärluft geöffnet, teilweise abgedeckt oder vollständig verschlossen werden. Dies kann beispielsweise durch geschlitzte zylindrische Hülsen erreicht werden, die federvorgespannt sind und die auf die Gaszufuhrleitung aufgebracht werden, um die radiale Öffnung teilweise oder vollständig zu verschließen.
Die US 182,952 A beschreibt eine Abdeckeinrichtung für einen Gasbrenner, die dazu eingerichtet ist, eine Gaszufuhrleitung des Gasbrenners zu umgreifen. Die Abdeckeinrichtung kann zum Abdecken einer radialen Öffnung der Gaszufuhrleitung relativ zu dieser verdreht werden.
Die EP 0 309 950 A2 beschreibt einen atmosphärischen Gasbrenner mit einer Abdeckung, die an einem Mischrohr des Gasbrenners vorgesehen ist, um den Anteil des Primärluftanteils im Gemisch bedarfsweise in Abhängigkeit vom jeweils örtlich vorhandenen Gasdruck zu regeln.
Die US 4,686,957 A beschreibt eine verdrehbare Abdeckeinrichtung zum Abdecken einer radialen Öffnung einer Gaszufuhrleitung.The present invention relates to a gas supply device for a gas burner with a covering device for covering a radial opening in a gas supply line for a gas burner and a cooking point. In order to achieve complete gas combustion, primary air is fed into a gas supply line of a gas burner. For this purpose, a radial opening may be provided on the gas supply line. Depending on the gas used, such as propane gas or town gas, a different volume flow of primary air is required. Thus, the gas burner is used for different types of gas, a cross-sectional area of the radial opening is adjustable. For this purpose, the radial opening can be opened according to the required amount of primary air, partially covered or completely closed. This can be achieved, for example, by slotted cylindrical sleeves which are spring-biased and which are applied to the gas supply line to partially or completely close the radial opening.
The US 182,952 A describes a cover device for a gas burner, which is adapted to encompass a gas supply line of the gas burner. The cover may be rotated to cover a radial opening of the gas supply line relative thereto.
The EP 0 309 950 A2 describes an atmospheric gas burner with a cover which is provided on a mixing tube of the gas burner to regulate the proportion of the primary air fraction in the mixture, if necessary, depending on the respective local gas pressure.
The US 4,686,957 A describes a rotatable cover device for covering a radial opening of a gas supply line.

Die US 3,351,118 A beschreibt eine Abdeckeinrichtung zum Abdecken einer radialen Öffnung einer Gaszufuhrleitung. Die Abdeckeinrichtung umfasst ein Verdrehsicherungselement, das formschlüssig eine außenseitig an der Gaszufuhrleitung vorgesehene Rippe umgreift, um ein Verdrehen der Abdeckeinrichtung relativ zu der Gaszufuhrleitung zu verhindern.
Die US 3,905,756 A beschreibt eine Abdeckeinrichtung zum Abdecken einer radialen Öffnung einer Gaszufuhrleitung. Zum Freigeben und Abdecken der Öffnung ist die Abdeckeinrichtung relativ zu der Gaszufuhrleitung verdrehbar.
Die US 1,406,614 A beschreibt eine Abdeckeinrichtung zum Abdecken einer radialen Öffnung einer Gaszufuhrleitung. Die Abdeckeinrichtung ist relativ zu der Gaszufuhrleitung axial verschiebbar und verdrehbar, um die Öffnung abzudecken oder freizugeben.
Die US 2,494,881 A beschreibt einen Halteclip für eine Rohrleitung. Der Halteclip weist einen Umgreifabschnitt zum Umgreifen der Rohrleitung auf. Die GB142159 beschreibt ebenfalls eine Abdeckeinrichtung zum Abdecken einer radialen Öffnung einer Gaszufuhreinrichtung. Vor diesem Hintergrund besteht eine Aufgabe der vorliegenden Erfindung darin, eine verbesserte und leicht handhabbare Gaszufuhreinrichtung für einen Gasbrenner zur Verfügung zu stellen.
Demgemäß wird eine Gaszufuhreinrichtung für einen Gasbrenner mit einer Gaszufuhrleitung, die zwei radiale Öffnungen aufweist, und einer Abdeckeinrichtung zum Abdecken der radialen Öffnungen gemäß Anspruch 1 vorgeschlagen. Die Abdeckeinrichtung ist dazu eingerichtet, eine Querschnittsfläche der radialen Öffnung der Gaszufuhrleitung zu verändern, insbesondere zu verkleinern. Mittels des Handhabungsabschnitts kann die Abdeckeinrichtung leicht und ohne Werkzeug radial auf die Gaszufuhrleitung aufgeschoben werden. Insbesondere ist der Umgreifabschnitt derart federvorgespannt, dass er beim Aufschieben auf die Gaszufuhrleitung aufgebogen wird und diese somit zumindest teilweise formschlüssig umgreift. Insbesondere ist in einem demontierten Zustand der Abdeckeinrichtung ein Innendurchmesser des Umgreifabschnitts kleiner als ein Außendurchmesser der Gaszufuhrleitung. Hierdurch kann eine Federvorspannung des Umgreifabschnitts erreicht werden. Die Abdeckeinrichtung kann bei einem in eine Kochstelle eingebauten Gasbrenner schnell und komfortabel montiert, demontiert oder ausgetauscht werden. Hierdurch ist eine hohe Flexibilität bei dem verwendeten Brennstoff erreichbar. Vorzugsweise sind die Gaszufuhrleitung und der Umgreifabschnitt derart ausgestaltet, dass der Umgreifabschnitt eine radiale Haltekraft in Richtung zu der Gaszufuhrleitung ausübt. Zwischen dem Umgreifabschnitt und der Zufuhrleitung kann ein Dichtmittel vorgesehen sein. Erfindungsgemäß weist die Abdeckeinrichtung zwei Verdrehsicherungselemente auf. Die Verdrehsicherungselemente können beispielsweise in an einer Außenseite der Gaszufuhrleitung vorgesehene Bohrungen, Rippen, Vorwölbungen oder dergleichen formschlüssig eingreifen. Durch das Verdrehsicherungselement ist eine wohldefinierte Positionierung der Abdeckeinrichtung an der Gaszufuhrleitung gewährleistet. Das Verdrehsicherungselement ermöglicht einen einfachen Einbau der Abdeckeinrichtung, da sich diese mittels des Verdrehsicherungselements selbsttätig an der Gaszufuhrleitung positioniert.
Das Verdrehsicherungselement ist dazu eingerichtet, in die radiale Öffnung der Gaszufuhrleitung einzugreifen, um ein Verdrehen der Abdeckeinrichtung relativ zu der Gaszufuhrleitung zu verhindern.The US 3,351,118 A describes a cover device for covering a radial opening of a gas supply line. The covering device comprises an anti-rotation element which engages in a form-fitting manner around a rib provided on the outside of the gas supply line in order to prevent the covering device from rotating relative to the gas supply line.
The US 3,905,756 A describes a cover device for covering a radial opening of a gas supply line. To release and cover the opening, the covering device is rotatable relative to the gas supply line.
The US 1,406,614 A describes a cover device for covering a radial opening of a gas supply line. The cover means is axially slidable and rotatable relative to the gas supply line to cover or release the opening.
The US 2,494,881 A describes a retaining clip for a pipeline. The retaining clip has a Umgreifabschnitt for grasping the pipeline. The GB142159 also describes a cover device for covering a radial opening of a gas supply device. Against this background, an object of the present invention is to provide an improved and easy-to-handle gas supply device for a gas burner.
Accordingly, a gas supply device for a gas burner with a gas supply line, which has two radial openings, and a covering device for covering the radial openings according to claim 1 is proposed. The covering device is designed to change a cross-sectional area of the radial opening of the gas supply line, in particular to reduce it. By means of the handling section, the cover device can be slid radially and without tools radially onto the gas supply line. In particular, the gripping portion is spring biased so that it is bent when pushed onto the gas supply line and thus at least partially positively engages around. In particular, in a disassembled state of the cover, an inner diameter of the Umgreifabschnitts is smaller than an outer diameter of the gas supply line. In this way, a spring bias of the Umgreifabschnitts be achieved. The cover can be quickly and easily installed, disassembled or replaced in a built-in gas hob gas burner. As a result, a high flexibility in the fuel used can be achieved. Preferably, the gas supply line and the Umgreifabschnitt are designed such that the Umgreifabschnitt exerts a radial holding force in the direction of the gas supply line. Between the Umgreifabschnitt and the supply line, a sealing means may be provided. According to the invention, the covering device has two anti-rotation elements. The anti-rotation elements can intervene in a form-fitting manner, for example, in bores, ribs, protrusions or the like provided on an outer side of the gas supply line. The anti-rotation element ensures a well-defined positioning of the covering device on the gas supply line. The anti-rotation element allows easy installation of the cover, since it is automatically positioned by means of the anti-rotation element to the gas supply line.
The anti-rotation element is adapted to engage in the radial opening of the gas supply line to prevent twisting of the cover relative to the gas supply line.

Vorzugsweise weist die Abdeckeinrichtung zwei Verdrehsicherungselemente auf, die in einander gegenüberliegende radiale Öffnungen der Gaszufuhrleitung eingreifen.Preferably, the cover device has two anti-rotation elements, which engage in opposite radial openings of the gas supply line.

Insbesondere greift das Verdrehsicherungselement formschlüssig in die radiale Öffnung ein. Das Verdrehsicherungselement gewährleistet eine bessere Abdichtung der radialen Öffnung.In particular, the anti-rotation element engages positively in the radial opening. The anti-rotation ensures a better seal the radial opening.

Gemäß einer weiteren Ausführungsform erstreckt sich das Verdrehsicherungselement aus dem Umgreifabschnitt heraus in Richtung zu der Gaszufuhrleitung hin.According to a further embodiment, the anti-rotation element extends out of the gripping portion in the direction of the gas supply line.

Der Umgreifabschnitt weist beispielsweise eine Zylinderform mit einem umlaufenden Wandabschnitt aus, aus dem sich das Verdrehsicherungselement heraus erstreckt. Das Verdrehsicherungselement erstreckt sich vorzugsweise zu einer Mittelachse des zylindrischen Umgreifabschnitts hin. Das Verdrehsicherungselement kann beispielsweise als Abkantung des Umgreifabschnitts ausgebildet sein. Das Verdrehsicherungselement ist insbesondere materialeinstückig mit dem Umgreifabschnitt ausgebildet. Dadurch, dass das Verdrehsicherungselement vorzugsweise als Abkantung des Umgreifabschnitts ausgebildet ist, ist eine einfache und kostengünstige Herstellung der Abdeckeinrichtung möglich.The Umgreifabschnitt has, for example, a cylindrical shape with a circumferential wall portion from which extends the anti-rotation element out. The anti-rotation element preferably extends toward a central axis of the cylindrical gripping portion. The anti-rotation element may for example be formed as a fold of Umgreifabschnitts.

Die Figur 1 zeigt eine schematische perspektivische Ansicht eines Gasbrenners 1. Der Gasbrenner 1 kann einen Innenbrenner 2 und einen Außenbrenner 3 aufweisen. Der Innenbrenner 2 kann in dem Außenbrenner 3 aufgenommen sein. Der Gasbrenner 1 weist ferner eine Zündeinrichtung 4 und ein Brennerhaus oder Gehäuse 5 auf. Der Gasbrenner 1 kann eine Gaszufuhreinrichtung 6 des Innenbrenners 2 und eine Gaszufuhreinrichtung 7 des Außenbrenners 3 aufweisen. Im Folgenden wird lediglich auf die Gaszufuhreinrichtung 6 des Innenbrenners 2 eingegangen. Die Gaszufuhreinrichtung 7 des Außenbrenners 3 kann analog zu der Gaszufuhreinrichtung 6 des Innenbrenners 2 ausgebildet sein.The FIG. 1 shows a schematic perspective view of a gas burner 1. The gas burner 1, an internal burner 2 and an external burner 3 have. The inner burner 2 may be accommodated in the outer burner 3. The gas burner 1 also has an ignition device 4 and a burner house or housing 5. The gas burner 1 may have a gas supply device 6 of the internal burner 2 and a gas supply device 7 of the external burner 3. In the following, only the gas supply device 6 of the internal burner 2 will be discussed. The gas supply device 7 of the outer burner 3 may be formed analogously to the gas supply device 6 of the inner burner 2.

Die Gaszufuhreinrichtung 6 weist eine Gaszufuhrleitung 8 auf. Die Gaszufuhrleitung 8 ist vorzugsweise rohrförmig. Die Gaszufuhreinrichtung 6 ist in Figur 2 in einer schematischen Schnittansicht gezeigt. Die Gaszufuhrleitung 8 kann eine Mischleitung des Gasbrenners 1 sein. In der Gaszufuhrleitung 8 wird ein gasförmiger Brennstoff wie beispielsweise Erdgas, Stadtgas, Flüssiggas oder dergleichen mit Primärluft vermischt. In der Figur 2 ist der durch die Gaszufuhrleitung 8 strömende gasförmige Brennstoff mit einem Pfeil 9 gekennzeichnet.The gas supply device 6 has a gas supply line 8. The gas supply line 8 is preferably tubular. The gas supply device 6 is in FIG. 2 in a schematic Section view shown. The gas supply line 8 may be a mixing line of the gas burner 1. In the gas supply pipe 8, a gaseous fuel such as natural gas, city gas, LPG or the like is mixed with primary air. In the FIG. 2 the gaseous fuel flowing through the gas supply line 8 is marked with an arrow 9.

Die Gaszufuhrleitung 8 weist zumindest eine radiale Öffnung 10 auf. Die radiale Öffnung 10 weist, wie in der Figur 3 gezeigt, eine Querschnittsfläche A auf. Vorzugsweise sind an der Gaszufuhrleitung 8 zwei einander gegenüberliegende radiale Öffnungen 10, 11 vorgesehen. Die Öffnungen 10, 11 sind vorzugsweise rechteckförmig mit abgerundeten Ecken ausgebildet. Im Folgenden wird zur Vereinfachung lediglich auf die Öffnung 10 eingegangen. Die Öffnung 10 weist beispielsweise eine Länge I und eine Breite r auf.The gas supply line 8 has at least one radial opening 10. The radial opening 10 has, as in the FIG. 3 shown, a cross-sectional area A on. Preferably, two opposing radial openings 10, 11 are provided on the gas supply line 8. The openings 10, 11 are preferably formed rectangular with rounded corners. In the following, only the opening 10 will be discussed for the sake of simplicity. The opening 10 has, for example, a length I and a width r.

Durch die radiale Öffnung 10 kann Primärluft in die Gaszufuhrleitung 8 strömen und sich mit dem dort befindlichen gasförmigen Brennstoff mischen. Das Einströmen der Primärluft durch die Öffnung 10 ist in der Figur 2 mittels eines Pfeils 12 illustriert. Je nach der Art des verwendeten Brennstoffs ist ein höherer oder ein geringerer Volumenstrom an Primärluft erforderlich. Der Volumenstrom an Primärluft durch die Öffnung 10 ist abhängig von der Größe der Querschnittsfläche A. Um die Menge an einströmender Primärluft zu steuern, kann die Öffnung 10 mit einer Abdeckeinrichtung 13 vollständig oder teilweise abgedeckt sein. Die Abdeckeinrichtung 13 ist dazu eingerichtet, die Querschnittsfläche A der radialen Öffnung zu ändern, insbesondere zu verkleinern.Through the radial opening 10 primary air can flow into the gas supply line 8 and mix with the gaseous fuel located there. The inflow of the primary air through the opening 10 is in the FIG. 2 illustrated by an arrow 12. Depending on the type of fuel used, a higher or lower volume flow of primary air is required. The volume flow of primary air through the opening 10 is dependent on the size of the cross-sectional area A. In order to control the amount of inflowing primary air, the opening 10 may be completely or partially covered with a covering device 13. The covering device 13 is adapted to change the cross-sectional area A of the radial opening, in particular to reduce it.

Die Abdeckeinrichtung 13 kann dazu eingerichtet sein, die radiale Öffnung 10 vollständig oder lediglich teilweise abzudecken. Die radiale Öffnung 10 kann auch mit mehreren nebeneinander angeordneten Abdeckeinrichtungen 13 abgedeckt sein. Die Abdeckeinrichtung 13 weist einen Umgreifabschnitt 14 auf, der dazu eingerichtet ist, die Gaszufuhrleitung 8 zumindest teilweise formschlüssig zu umgreifen und die radiale Öffnung 10 abzudecken. Die Abdeckeinrichtung 13 kann ein Dichtmittel aufweisen, das zwischen dem Umgreifabschnitt 14 und der Gaszufuhrleitung 8 angeordnet ist.The cover device 13 may be configured to cover the radial opening 10 completely or only partially. The radial opening 10 may also be covered with a plurality of cover devices 13 arranged next to one another. The cover device 13 has a gripping portion 14, which is adapted to at least partially encompass the gas supply line 8 in a form-fitting manner and to cover the radial opening 10. The covering device 13 may have a sealing means which is arranged between the gripping section 14 and the gas supply line 8.

Die Abdeckeinrichtung 13 ist in den Figuren 4 und 5 gezeigt. Der Umgreifabschnitt 14 weist eine hohlzylindrische Form mit einer Mittelachse 15 auf. Der Umgreifabschnitt 14 kann zwei einander gegenüberliegende Unterbrechungen seiner Wandung aufweisen. An dem Umgreifabschnitt 14 angeordnet ist ein Handhabungsabschnitt 16, der vorzugsweise materialeinstückig mit dem Umgreifabschnitt 14 ausgebildet ist. Der Handhabungsabschnitt 16 weist bevorzugt eine Omegaform auf und geht in die Wandung des Umgreifabschnitts 14 über. Der Handhabungsabschnitt 16 dient dem Handhaben der Abdeckeinrichtung 13 bei einem radialen Aufschieben derselben in radialer Richtung R auf die Gaszufuhrleitung 8. Man kann bei der Abdeckeinrichtung 13 von einem Clips oder einer Klammer sprechen, die zum Umklammern der Gaszufuhrleitung 8 dient. Eine Breite b des Umgreifabschnitts 14 kann größer sein als die Länge I der radialen Öffnung 10. Alternativ kann die Breite b kleiner als die Länge der radialen Öffnung I sein. Beispielsweise können für verschiedene Brennstofftypen Abdeckeinrichtungen 13 mit verschiedenen Breiten b eingesetzt werden.
Falls in Ausführungsformen der Abdeckeinrichtung 13 die Breite b des Umgreifabschnitts 14 größer ist als die Länge I der radialen Öffnung 10, kann der Umgreifabschnitt 14 die radiale Öffnung 10 vollständig abdecken. Der Handhabungsabschnitt 16 weist vorzugsweise die gleiche Breite auf wie die Breite b des Umgreifabschnitts 14. Der Handhabungsabschnitt 16 ist vorzugsweise elastisch verformbar.
Gegenüberliegend dem Handhabungsabschnitt 16 kann ein Einführabschnitt 17 der Abdeckeinrichtung 13 vorgesehen sein. Der Einführabschnitt 17 weist vorzugsweise zwei Einführarme 18, 19 auf. Die Einführarme 18, 19 sind gekrümmt, wobei deren Endabschnitte voneinander weg weisen. Der Einführabschnitt 17 ist vorzugsweise materialeinstückig mit dem Umgreifabschnitt 14 ausgebildet. Die Einführarme 18, 19 sind dazu eingerichtet, dass diese sich bei einem radialen Aufschieben der Abdeckeinrichtung 13 in Richtung R zu der Gaszufuhrleitung 8 voneinander weg bewegen, wobei der Handhabungsabschnitt 16, der Umgreifabschnitt 14 und/oder die Einführarme 18, 19 elastisch verformt werden. Die Abdeckeinrichtung 13 ist insbesondere als Blechbiegebauteil ausgeführt. Vorzugsweise weist die Abdeckeinrichtung 13 einen Federstahl auf. Das heißt, die Abdeckeinrichtung 13 ist vollständig oder teilweise mit einem Federstahl gebildet. Hierdurch ergeben sich gute Halteeigenschaften der Abdeckeinrichtung 13, da diese die Gaszufuhrleitung 8 umklammert. Erfindungsgemäß weist die Abdeckeinrichtung 13 zwei Verdrehsicherungselemente 20, 21 auf. Je nachdem, ob die Gaszufuhrleitung eine oder zwei Öffnungen 10, 11 aufweist, weist entsprechend die Abdeckeinrichtung 13 ein oder zwei Verdrehsicherungselemente 20, 21 auf. Das Verdrehsicherungselement 20 liegt an einem Rand der radialen Öffnung 10 auf, und das Verdrehsicherungselement 21 liegt an einem Rand der radialen Öffnung 11 derart auf, dass die Abdeckeinrichtung 13 relativ zu einer Mittelachse 22 der Gaszufuhrleitung 8 gegen ein Verdrehen gesichert ist.
Die Verdrehsicherungselemente 20, 21 sind vorzugsweise einteilig mit dem Umgreifabschnitt 14 ausgebildet. Die Verdrehsicherungselemente 20, 21 erstrecken sich aus dem Umgreifabschnitt 14 heraus in Richtung der Mittelachse 15 desselben bzw. in Richtung zu der Gaszufuhrleitung 8 hin. Die Verdrehsicherungselemente 20, 21 sind vorzugsweise als Abkantungen des Umgreifabschnitts 14 ausgebildet. Das heißt, die Verdrehsicherungselemente 20, 21 sind senkrecht zu dem Umgreifabschnitt 14 verformte Abschnitte desselben. Unter "senkrecht" ist vorliegend ein Winkel von 90° ± 10°, bevorzugt 90° ± 5°, weiter bevorzugt 90° ± 1° zu verstehen.
Die Abdeckeinrichtung 13 weist den Umgreifabschnitt 14 auf, der dazu eingerichtet ist, die Gaszufuhrleitung 8 zumindest teilweise formschlüssig zu umgreifen und die radiale Öffnung 10 abzudecken. An dem Umgreifabschnitt 14 ist der Handhabungsabschnitt 16 zum Handhaben der Abdeckeinrichtung 13 bei einem radialen Aufschieben desselben auf die Gaszufuhrleitung 8 angeordnet. Alle weiteren zuvor erläuterten Elemente sind lediglich optionale Bestandteile der Abdeckeinrichtung 13.
Eine Gaskochstelle 23 weist einen wie zuvor beschriebenen Gasbrenner 1 und eine wie zuvor beschriebene Gaszufuhreinrichtung 7 auf.
Obwohl die vorliegende Erfindung anhand von Ausführungsbeispielen beschrieben wurde, ist sie vielfältig modifizierbar.The cover 13 is in the FIGS. 4 and 5 shown. The gripping portion 14 has a hollow cylindrical shape with a central axis 15. The Umgreifabschnitt 14 may have two opposing interruptions of its wall. At arranged around the Umgreifabschnitt 14 is a handling portion 16, which is preferably formed integrally with the Umgreifabschnitt 14 material. The handling section 16 preferably has an omega shape and merges into the wall of the encompassing section 14. The handling portion 16 is used to handle the cover 13 in a radial pushing them in the radial direction R on the gas supply line 8. One can speak in the cover 13 of a clip or a clamp, which serves for clasping the gas supply line 8. A width b of the Umgreifabschnitts 14 may be greater than the length I of the radial opening 10. Alternatively, the width b may be smaller than the length of the radial opening I. For example, covering devices 13 with different widths b can be used for different types of fuel.
If in embodiments of the cover 13, the width b of the Umgreifabschnitts 14 is greater than the length I of the radial opening 10, the Umgreifabschnitt 14, the radial opening 10 completely cover. The handling section 16 preferably has the same width as the width b of the encompassing section 14. The handling section 16 is preferably elastically deformable.
Opposite the handling section 16, an insertion section 17 of the cover 13 may be provided. The insertion section 17 preferably has two insertion arms 18, 19. The insertion arms 18, 19 are curved with their end portions facing away from each other. The insertion section 17 is preferably formed in one piece with the gripping portion 14. The insertion arms 18, 19 are adapted to move away from each other with a radial sliding of the cover 13 in the direction R to the gas supply line 8, wherein the handling portion 16, the Umgreifabschnitt 14 and / or the insertion arms 18, 19 are elastically deformed. The covering device 13 is designed in particular as a sheet-metal bending component. Preferably, the cover 13 has a spring steel. That is, the cover 13 is completely or partially formed with a spring steel. This results in good retention properties of the cover 13, since this encloses the gas supply line 8. According to the invention, the covering device 13 has two anti-rotation elements 20, 21. Depending on whether the gas supply line has one or two openings 10, 11, accordingly, the cover 13 has one or two anti-rotation elements 20, 21. The anti-rotation element 20 rests on an edge of the radial opening 10, and the anti-rotation element 21 rests on an edge of the radial opening 11 such that the cover 13 is secured against rotation relative to a central axis 22 of the gas supply line 8.
The anti-rotation elements 20, 21 are preferably formed integrally with the Umgreifabschnitt 14. The anti-rotation elements 20, 21 extend out of the encompassing section 14 in the direction of the central axis 15 thereof or in the direction of the gas supply line 8. The anti-rotation elements 20, 21 are preferably formed as folds of Umgreifabschnitts 14. That is, the anti-rotation elements 20, 21 are perpendicular to the Umgreifabschnitt 14 deformed portions thereof. By "perpendicular" is meant an angle of 90 ° ± 10 °, preferably 90 ° ± 5 °, more preferably 90 ° ± 1 °.
