Abstract

The invention relates to a security mechanism for gas-heated apparatus. A displaceable member (15) controlled by a heat-sensitive element (16) is connected mechanically to a release lever (11) for the cocking mechanism (7, 6) of the tap (2) for admission of gas to the apparatus in order to cause the closure of the latter in the event of an increase in temperature. Application in gas-heated water boilers without a permanent pilot flame. <IMAGE>

85' 402 423 018 5 5 8 7 Saunier Duval Eau Chaude Chauffage - S.D.E.C.C. Patentansprüche85 '402 423 018 5 5 8 7 Saunier Duval Eau Chaude Chauffage - S.D.E.C.C. Claims 1. Sicherheitsvorrichtung für gasbeheizte Warmwasserbereiter ohne ständige Wachflamme, die den Warmwasserbereiter bei einer Störung in der Ableitung seiner Verbrennungsprodukte abzuschalten gestattet, die eine Spannhebelvorrichtung für das Gaszufuhrventil des Warmwasserbereiters aufweist, welche auf einen Auslösehebel einrastbar ist, dessen Schwenkbewegung das Entspannung und Schließen des Gaszufuhrventils unter der Wirkung einer Schließfeder bewirkt, und die einen Thermosensor aufweist, der auf eine Erhöhung der Temperatur im Bereich des Abzugs der Verbrennungsprodukte im Sinne einer Verschiebung eines ausdehnbaren Balges und seiner Wirkung eines Entsicherns und Schließens des Gaszufuhrventils reagiert,
dadurch gekennzeichnet, daß der ausdehnbare Balg (15) positiv auf den Auslösehebel (11) über eine bewegbare Muffe (17) wirkt, die von einer Feder (18) rückgestellt wird und einen Anschlag (19) sowie ein Tragteil (20) trägt, die ihren Bewegungen folgen.1.Safety device for gas-heated water heaters without a constant flame, which allows the water heater to be switched off in the event of a fault in the discharge of its combustion products, which has a clamping lever device for the gas supply valve of the water heater, which can be locked onto a release lever, the pivoting movement of which causes the expansion and closing of the gas supply valve the effect of a closing spring, and which has a thermal sensor that reacts to an increase in temperature in the area of the discharge of the combustion products in the sense of a displacement of an expandable bellows and its effect of unlocking and closing the gas supply valve,
characterized in that the expandable bellows (15) acts positively on the release lever (11) via a movable sleeve (17) which is reset by a spring (18) and carries a stop (19) and a support part (20) which follow their movements. 2. Sicherheitsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der Arm (13) des Auslösehebels (11) und ein Schwenkarm (21), dessen einer Endbereich sich in Anlage an einem anderen Arm des Auslösehebels (11) befindet, zwischen dem Anschlag (19) und dem Tragteil (20) angeordnet sind.2. Safety device according to claim 1, characterized in that that the arm (13) of the release lever (11) and a pivot arm (21), one end of which is in contact with another arm of the release lever (11) is located between the stop (19) and the support part (20) are arranged. 3. Sicherheitsvorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß ein verstellbarer Anschlag (13) an einem Arm des Auslösehebels (11) angeordnet ist und als Abstützung für den Schwenkarm (21) dient.
303. Safety device according to claim 2, characterized in that an adjustable stop (13) is arranged on one arm of the release lever (11) and serves as a support for the pivot arm (21).
