Key-(touch-) controlled gas range

A controlled gas range comprising:

• means for adjusting the flame intensity in a controlled manner;
• a continuous electronic ignition circuit;
• a valve;
• and
• a burner,
• characterized in that said valve includes a rotor defining a plurality of channels therein, a housing and a servo-motor connected to said rotor, a gas inlet and a gas outlet said gas outlet having a diameter slightly greater or equal to that of the largest channel within the rotor, said gas inlet and said gas outlet being respectively provided on said housing in an opposing relationship to each other, said gas inlet further being connected to a gas source and said gas outlet further being directed to the burner;
• said housing further including an upper face defining a small orifice with a diameter sufficient to supply the amount of gas for a base fire, said orofice being connected to and adjacent to said electronic ignition circuit of said burner by a tube;
• said plurality of channels including communicating channels and at least one blocked channel at symmetrical positions in said rotor, the size of said communicating channels being different for each symmetrical position, said communicating channels communicating with the center of said rotor so that there are channels with different sizes connected between said gas inlet and outlet under different rotating angles of said rotor thereby directing various amounts of gas to said burner, said gas inlet and said outlet both being blocked by said rotor when said rotor is rotated with an angle for said blocked channel to cut off the gas supply, said channels including one base fire channel which is blocked at one end so that the base fire channel is only connected between said gas inlet and said orifice when said rotor is rotated with an angle for said base fire channel.
