electric activated device to shut off the gas flame of one of several cooking units

摘要

The device has a magnetic valve (13) whose coil (12) is supplied by a thermoelement (11) and that is held in its open position by the thermoelement when it is heated by the gas flame. A switching device (22, 23) is provided for feeding a compensation current for causing the magnetic valve to drop into the closed position into the thermo-current circuit of the magnetic coil connected to the thermoelement.
