Abstract: Magnet-thermocouple for the fail-safe safety supply of gas to burners or the like, in particular of fail-safe safety control for domestic cooking devices, comprises: at least one gas burner, which gas burner is connected to a gas supply source by flame-regulating means and by means of a safety valve driven by a flame presence sensor consisting of a thermocouple, said safety valve having an open condition, wherein said supply source supplied said burner, and a closed condition, wherein the gas passage is interrupted and wherein the thermocouple, in the presence of a flame, generates an electrical signal constituting the drive signal for the passage of said safety valve from an open condition to a closed condition, and vice-versa, of said safety valve, whereas a further drive signal generator and power supply of said safety valve is provided, for the temporary and alternative supply of the safety valve during the flame ignition step heating the thermocouple, to the temperature generating the drive signal.

Abstract: An over or grill burner includes a hollow body with a supplying port receiving a gaseous fuel mixture and outlet holes emitting the gaseous fuel mixture, and a conveying duct conveying the gaseous fuel mixture toward the hollow body, which has a delivering port and a supplying/mixing port with a first aperture for a fuel gas and a second aperture for a gaseous combusting product, and a reflector conveying a flame produced by combustion of the fuel mixture from the outlet holes. The supplying port of the hollow body and the delivering port of the conveying duct have a substantially circular cross-section and are connected to each other in a freely rotatable manner.
