Abstract

Es wird eine Vorrichtung zum elektrisch gesteuerten Abschalten der Gasflamme einer Brennstelle (15) vorgeschlagen, der über ein Magnetventil (13) brennbares Gas zuführbar ist, wobei die Magnetspule (12) des Magnetventils (13) von einem Thermoelement (11) gespeist wird und das Magnetventil (13) bei durch die Gasflamme (18) erhitztem Thermoelement (11) in der Offenstellung gehalten wird. Eine Schalteinrichtung (22, 23) ist zum Einspeisen eines ein Abfallen des Magnetventils (13) in die Schließstellung bewirkenden Kompensationsstroms in den Thermostromkreis (10) der mit dem Thermoelement (11) verbundenen Magnetspule (12) vorgesehen. Hierdurch wird der sensible Thermostromkreis zum Abschalten nicht unterbrochen, und es werden schnellere Aufheizzeiten des Thermoelements erreicht.

The invention proposes a device for the electrically controlled switching off of the gas flame of a combustion station (15) to which combustible gas can be fed via a magnetic valve (13), the magnetic coil (12) of the solenoid valve (13) being fed by a thermocouple (11) and the Solenoid valve (13) is held by the gas flame (18) heated thermocouple (11) in the open position. A switching device (22, 23) is provided for feeding a compensation current causing the magnetic valve (13) to fall into the closed position into the thermo-current circuit (10) of the magnetic coil (12) connected to the thermocouple (11). As a result, the sensitive thermal circuit for switching off is not interrupted, and it will be faster heating times of the thermocouple achieved.
