EP 86 401 660.5 Saunier Duval ... PatentansprücheEP 86 401 660.5 Saunier Duval ... Patent claims 1. Injektionsvorrichtung mit doppeltem Ausstoß für eine Wachflamme eines Gasapparates des Typs Heißwasserbereiter oder Wasserkessel mit einer Einrichtung für die Steuerung und für die Gaszufuhr, die das Öffnen einer Umwegleitung ermöglicht, die für ein schnelles Spülen der in ihr enthaltenen Luft bestimmt ist und eine Zuführleitung für Gas dieser Wachflamme aufweist, die eine dem verwendeten Gas angepaßte Hauptdüse hat, wobei der Endbereich der Umwegleitung in Bezug auf die Achse der Zuführleitung der Hauptdüse geneigt angeordnet ist, dadurch gekennzeichnet, daß der Endbereich der Umwegleitung mit einer Zusatzdüse (5) ausgerüstet ist, deren Öffnung (8) einen größeren Durchmesser als die Öffnung der Hauptdüse (3) hat, und daß die zwei Düsen (3) und (5) von demselben Mischer (9) überdeckt sind, der oberhalb des Schnittpunktes (B) der Achse der beiden Leitungen (2) und (4) im wesentlichen zylindrisch wird und an das Rohr der Wachflamme (6) anschließt.1. Double-ejection injection device for a pilot flame of a gas appliance of the water heater or kettle type, comprising a control and gas supply device enabling the opening of a bypass line intended for rapid purging of the air contained therein and comprising a gas supply line for this pilot flame, which has a main nozzle adapted to the gas used, the end part of the bypass line being inclined with respect to the axis of the supply line of the main nozzle, characterized in that the end part of the bypass line is equipped with an additional nozzle (5) whose opening (8) has a larger diameter than the opening of the main nozzle (3), and in that the two nozzles (3) and (5) are covered by the same mixer (9) which becomes substantially cylindrical above the intersection point (B) of the axis of the two lines (2) and (4) and connects to the pilot flame tube (6). 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der mittlere Bereich des Mischers (9) in Nähe der Achse (AA*) der Zuführleitung (2) zylindrisch und in Nähe der Achse (BB') der Umwegleitung (4) konisch ist.2. Device according to claim 1, characterized in that the middle region of the mixer (9) is cylindrical near the axis (AA*) of the feed line (2) and conical near the axis (BB') of the bypass line (4). 3. Einrichtung nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, daß der untere Bereich (EF) des Mischers (9) eine bezogen auf den mittleren Bereich (DE) nach außen weisende Aufweitung hat.3. Device according to claims 1 and 2, characterized in that the lower region (EF) of the mixer (9) has an outward-facing widening relative to the middle region (DE). 4. Vorrichtung nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, daß die Zusatzdüse (5) auf einem höheren Niveau als die Hauptdüse (3) und zumindest im Niveau der Basis (FF') des Mischers (9) mündet.4. Device according to claims 1 and 2, characterized in that the additional nozzle (5) opens at a higher level than the main nozzle (3) and at least at the level of the base (FF') of the mixer (9). 5. Vorrichtung nach den Ansprüchen 1 und 4, dadurch gekennzeichnet, daß die Basis (FF') des Mischers (9) im Bereich der Zusatzdüse (5) geringfügig geneigt und höher ist.5. Device according to claims 1 and 4, characterized in that the base (FF') of the mixer (9) is slightly inclined and higher in the region of the additional nozzle (5).
