The invention relates to a method and an arrangement for igniting a gas flow by means of remote control. The aim of the invention is to maintain the current consumption so low that an integratable voltage source can be used. To this end, a thermoelectric safety pilot valve () is opened and the escaping gas ignited by the actuation of an electronic control unit () fed by a voltage source. Said thermoelectric safety pilot valve () is maintained open by a safety pilot magnet () by means of a holding current from the voltage source until a thermocouple () provides the required holding current once the gas flow has been ignited or a defined holding time is exceeded.

Method and arrangement for igniting a gas flow

The invention relates to a method and a circuit for igniting a gas flow in a fully automatic manner. The aim of the invention is to maintain the necessary current consumption so low that an integratable voltage source can be used. To this end, once an electronic control unit has been activated, a thermoelectric safety pilot valve () is opened by an electromagnet which is temporarily excited by a rush of current, is maintained in the open position by a safety pilot magnet () by means of a holding current provided by a voltage source (), and the escaping gas is ignited. Once a thermoelectric couple () is provided for the necessary holding current, the voltage source () is switched off. In the event of damage, the method is automatically interrupted.

Method and circuit for igniting a gas flow

The aim of the invention is to create a gas regulating fitting which, once a gas stove has been successfully started up, can switch the pilot burner into the off position when the main burner is in the off position, in order to maintain the power consumption of the gas stove as low as possible. The aim of the invention is also to provide the gas regulating fitting with as simple a structure as possible. To this end, the gas regulating fitting comprises a sensor () by which means the operating state of the main burner () can be detected. The sensor () is connected to a thermoelectric safety pilot valve () in such a way that, when the operating state of the main burner () is switched from the on position into the off position by a signal emitted from the sensor (), the thermoelectric safety pilot valve () assumes the closed position thereof. The gas regulating fitting can be used to ignite and to regulate a gas flow flowing to a burner.
