Abstract

According to the invention the said valve comprises a rotary actuating knob (1) and a bubbling diaphragm mechanism (8, 4) connected to a bulb and reacting to an increase in temperature of the combustion products. It also comprises a cam (2) mounted so as to rotate about its axis AA' under the action of the said knob which cooperates with the actuating rod (7, 21) of the gas inlet shutter (6) and which can also move in translation over the said axis AA' under the action of the bubbling diaphragm mechanism (8) in order to cause it to be released from the actuating rod (7) of the shutter and to make the apparatus safe. Application to hot water apparatuses without a permanent pilot flame. <IMAGE>

Sicherheitsventil nach Anspruch 2,
dadurch gekennzeichnet, daß eine Erzeugende des exzentrischen Abschnitts (25) eine Erzeugende des Abschnitts (23) mit dem kleinen Durchmesser verlängert, und daß eine weitere diametral gegenüberliegende Erzeugende des exzentrischen Abschnitts eine Erzeugende des Abschnitts (24) mit dem größeren Durchmesser verlängert.3. Safety valve according to claim 2,
characterized in that a generatrix of the eccentric portion (25) extends a generatrix of the portion (23) with the small diameter, and that a further diametrically opposite generatrix of the eccentric portion extends a generatrix of the portion (24) with the larger diameter. 4. Sicherheitsventil nach den Ansprüchen 1, 2 und 3, dadurch gekenn &zgr; e i chnet, daß die Achse (7) zur Betätigung der Stellstange (21) der Klappe (6) gegen den Rand des Zwischenabschnitts (25) der Nocke (2) anliegt und über den zylinderförmigen Abschnitt (23) mit geringerem Durchmesser vorsteht.4. Safety valve according to claims 1, 2 and 3, characterized in that the axis (7) for actuating the actuating rod (21) of the flap (6) rests against the edge of the intermediate section (25) of the cam (2) and protrudes beyond the cylindrical section (23) with a smaller diameter. 5. Sicherheitsventil nach Anspruch 1 und 2, dadurch gekennz eichnet, daß die Einrichtung mit der Membrane (8) unter Zwischenschaltung eines Hebels (4) auf eine Stellschraube (9) einwirkt, die mit der Nocke (2) verbunden ist, wobei der Aufbau aus Schraube und Nocke auf einer festen Stange (3) längs der Achse AA1 gleiten kann.5. Safety valve according to claims 1 and 2, characterized in that the device with the membrane (8) acts, with the interposition of a lever (4), on an adjusting screw (9) which is connected to the cam (2), the assembly consisting of the screw and the cam being able to slide on a fixed rod (3) along the axis AA 1 . 6. Sicherheitsventil nach Anspruch 5,
dadurch gekennzeichnet, daß der Hebel (4) auf die Stellschraube (9) im Sinne einer Verlängerung der Nocke (2) des Betätigungsknopfes (1) gegenüber der Rückstellkraft einer Feder (13) einwirkt.6. Safety valve according to claim 5,
characterized in that the lever (4) acts on the adjusting screw (9) in the sense of an extension of the cam (2) of the actuating button (1) against the restoring force of a spring (13). 7. Sicherheitsventil nach Anspruch 5,
dadurch gekennzeichnet, daß der Abstand zwischen der Schraube (9) und der Nocke (2) durch die beide Teile miteinander verbindende Schraubverbindung regelbar ist.7. Safety valve according to claim 5,
characterized in that the distance between the screw (9) and the cam (2) can be regulated by the screw connection connecting the two parts together.
