Regulating valve for a gas cooking appliance and gas cooking appliance incorportating said regulating valve

A gas regulating valve capable of regulating a flow of a first gas and a flow of a second gas, the gas regulating valve comprising:

• a valve body having an inlet conduit through which gas is supplied, a first outlet conduit and an inner cavity in fluid communication with the inlet conduit, the valve body including a first internal through hole that fluidly communicates the inner cavity with the first outlet conduit;
• a rotating disc including a first plurality of connecting holes of different sizes arranged in a first angular path, the rotating disc rotatable in the inner cavity to cause an overlap of at least one or more of the first plurality of connecting holes with the first inner through hole of the valve body to cause the inner cavity to be in fluid communication with the first outlet conduit to regulate the flow of the first gas or to regulate the flow of the second gas, the rotating disc having a surface in contact with a surface of the valve body that at least partially demarcates the inner cavity and rotatable with respect to the surface of the valve body, a leak-tight seal existing between the surface of the rotating disc and the surface of the valve body;
• and
• a rotatable actuating shaft having a central axis and coupled to the rotating disc in manner that results in a rotation of the rotating disc upon there being a rotation of the actuating shaft, the actuating shaft capable of assuming a first angular position and a second angular position with respect to the rotating disc, the first angular position corresponding to the regulation of the flow of the first gas through the regulation valve through use of a first set of the first plurality of connecting holes in the rotating disc, the second angular position corresponding to the regulation of the flow of the second gas through the regulation valve through use of a second set of the first plurality of connecting holes in the rotating disc, the second set of the first plurality of connecting holes being different than the first set of the first plurality of connecting holes, the first and second sets having in common some of the first plurality of connecting holes.
