Abstract: A method and a system for igniting a gas burner of a gas stove is disclosed, which includes a spark generating circuit to produce sparks for igniting gas burners and a plurality of electrodes which are connected with the spark generating circuit for the ignition of the gas burners. A flame sensor circuit is operated in a first period for producing sparks, through of the electrodes, and in a second period and once the gas burner has been ignited, for sensing the presence of flame on each gas burner. A power source is connected for limiting the voltage to the flame sensor circuit.

Abstract: In an electronic ignition system for igniting a plurality of gas burners by means of a plurality of electrodes, each one being mounted adjacent with each burner for producing sparks for the ignition of each burner. A spark generating circuit connected with the electrodes in order to produce the sparks for igniting each burner. And a power source connected to the spark generating circuit. A flame sensor circuit is connected to the spark generating circuit and at least one electrode, which in a first period and once the spark generating circuit has been activated for igniting each electrode, the flame sensor circuit is operated to detect the absence of flame on the burner by means of said electrode, and once that the burner has been ignited, the electrode and flame sensor circuit are operated for sensing the presence of flame on the burner.

Abstract: A linear turn down valve structure is disclosed, for gaseous fuels. The valve structure can advantageously be produced with aluminum alloys of die-casting grade, by means of a squeeze die-casting process. The valve structure comprises a valve body and a cap having register members to provide a self positioning and assembly of the main components of the valve. This eliminates the possibility of radial and axial misalignment thereof and secures a gas tight connection; a valve plug having passages in cooperation with a cap cam having three steps, to allow the safe switching of the continuous gas flow from maximum to minimum flow positions, as well as a safe turn-off position in a single operation; and a minimum flow control device to allow flow metering in order to permit the burners to operate with a wide variety of commercial gaseous fuels.

Abstract: The present invention is referred to a gas injector for a stove burner and its method of manufacture. The injector includes: a gas pipe located at the body of a domestic gas stove burner which itself includes: an area that is externally deformed with a semi-flattened out flange, near the end of the stated pipe which itself is attached to the burner; a threaded section on the internal part of the stated pipe, on top of the first area of the said deformed pipe; and, an upper flange which extends to the end of the pipe and does so angularly towards a greater diameter, preferably about a 45 degree angle relative to its axial shaft.
