ABSTRACT:
A safety valve supply circuit for the ignition of a gas burner is disclosed. Said safety valve is directly supplied by a flame-detecting thermocouple, and said supply circuit comprises a supply capacitor that is charged from an alternating mains voltage, obtaining from the energy accumulated in said supply capacitor, due to said charging, an input voltage signal that is used to temporarily supply said safety valve in order to maintain it open. Said charging of the supply capacitor is carried out by momentarily activating a supply switch to temporarily connect said supply capacitor to said alternating mains voltage, said supply switch activation occurring concurrently with the activation of the gas burner. Said supply circuit also comprises conditioning means for converting said input voltage signal into an output voltage signal that is directly applied to said safety valve to supply it, and so maintain it open.
