Abstract
A cooking appliance equipped with at least one regulating valve having a rotary regulator organ. The rotary regulator organ has an actuating shaft a plurality of peripheral openings adapted for regulating a flow of gas through the regulating valve. In a first angular position the rotary regulator organ is adapted to supply a constant flow Qmin of a first type of fuel through a first peripheral opening. In a second angular position, successive to the first angular position, the rotary regulator organ is adapted to supply a constant flow Qmin of a second type of fuel through a second peripheral opening. In one implementation a feature that rotates with the actuating shaft is adapted to engage a feature on the cooking appliance to limit the rotation of the rotary regulator organ to the first angular position.
