The gas ring has an operating button which simultaneously controls the gas supply (25). It has a pulsed air supply (6) with a valve (30) for adjusting its flow rate. When the operating button is activated it activates a micro-interrupter which causes the continuous supply of pulsed air in the direction of the burner (11). The air flow is controlled by a cam whose rotation is activated by the operating button. A lever system is held in contact with the cam by a spring, with a cable connected to the lever controlling the valve to move between different obturating positions in the inlet air opening (4) located upstream of the pulsed air delivery. |
