A regulation valve having a valve body with a gas inlet. Housed within the valve body is a rotary regulatory body having a first inlet orifice corresponding to a first minimum flow of a first type of gas and a second inlet orifice corresponding to a second minimum flow of a second type of gas. The first and second inlet orifices are angularly displaced so that when the regulatory body assumes a first angular position within the regulatory body the first inlet orifice faces the gas inlet and so that when the regulatory body assumes a second angular position within the regulatory body the second inlet orifice faces the gas inlet. The regulation valve includes first and second sets of cooperating features that are capable of limiting rotation of the regulatory body to the first and second angular positions, respectively.

1. A regulation valve for supplying either a first type of gas or a second type of gas to a gas burner, the regulation valve comprising: a valve body having a gas inlet,a rotary regulatory body housed in said valve body, the regulatory body having a first inlet orifice corresponding to a first minimum flow of the first type of gas, and a second inlet orifice corresponding to a second minimum flow of the second type of gas, the rotary regulatory body rotates about a rotation axis between at least first, second and third successive angular positions, the first angular position corresponding to an off position, the first inlet orifice situated in the rotary regulatory body so that it is aligned to face the gas inlet when the rotary regulatory body is in the second angular position, the second inlet orifice situated in the rotary regulatory body so that it is aligned to face the gas inlet when the rotary regulatory body is in the third angular position,a drive shaft attached to the rotary regulatory body, a radially extending projection is coupled to the drive shaft and cooperates with another part of the regulation valve to limit the angular rotation of the rotary regulatory body to the third angular position where the second inlet orifice is aligned to face the gas inlet, andan elongate stop element having a proximal end section and a distal end section, the elongate stop element situated in a housing arranged on the valve body, the housing having an elongate passage with a proximal end and a distal end, the elongate stop element and the elongate passage each having a central axis that is substantially parallel to the rotation axis of the rotary regulatory body, the elongate stop element moveable within the elongate passage between a first axial position and a second axial position, in the first axial position the distal end section of the elongate stop element extends beyond the distal end of the elongate passage to interact with the radially extending projection that is coupled to the drive shaft to limit the angular rotation of the rotary regulatory body to the second angular position where the first inlet orifice is aligned to face the gas inlet, in the second axial position the distal end section of the elongate stop element does not extend beyond the distal end of the elongate passage to interact with the radially extending projection that is coupled to the drive shaft thereby permitting the rotary regulatory body to be rotated to the third angular position. 2. A regulation valve according to claim 1, wherein the first type of gas is natural gas and the second type of gas is liquid petroleum gas. 3. A regulation valve according to claim 1, wherein the distal end section of the elongate stop element comprises a threaded section, the elongate passage comprising an unthreaded proximal section and a threaded distal section, the elongate stop element being in the first axial position when the threaded section of the elongate stop element is threaded through the threaded distal section of the elongate passage. 4. A regulation valve according to claim 3, wherein the unthreaded proximal section of the elongate passage has a length sufficient to prevent the proximal end section of the elongate stop element from protruding from the housing when the elongate stop element is in the second axial position. 5. A regulation valve according to claim 1, wherein the valve body comprises a main body and a cover, the housing being a part of the cover. 6. A gas cooking appliance having a gas burner adapted for burning either a first type of gas or a second type of gas, the gas cooking appliance comprising at least one regulation valve for supplying either the first type of gas or the second type of gas to the gas burner, the regulation valve comprising a valve body having a gas inlet, a rotary regulatory body housed in said valve body, the rotary regulatory body having a first inlet orifice corresponding to a first minimum flow of the first type of gas, and a second inlet orifice corresponding to a second minimum flow of the second type of gas, the rotary regulatory body rotates about a rotation axis between at least first, second and third successive angular positions, the first angular position corresponding to an off position, the first inlet orifice situated in the rotary regulatory body so that it is aligned to face the gas inlet when the rotary regulatory body is in the second angular position, the second inlet orifice situated in the rotary regulatory body so that it is aligned to face the gas inlet when the rotary regulatory body is in the third angular position, a drive shaft attached to the rotary regulatory body, a radially extending projection is attached to the drive shaft and cooperates with another part of the regulation valve to limit the angular rotation of the rotary regulatory body to the third angular position where the second inlet orifice is aligned to face the gas inlet, and an elongate stop element having a proximal end section and a distal end section, the elongate stop element situated in a housing arranged on the valve body, the housing having an elongate passage with a proximal end and a distal end, the elongate stop element and the elongate passage each having a central axis that is substantially parallel to the rotation axis of the rotary regulatory body, the elongate stop element moveable within the elongate passage between a first axial position and a second axial position in the first axial position the distal end section of the elongate stop element extends beyond the distal end of the elongate passage to interact with the radially extending projection that is coupled to the drive shaft to limit the angular rotation of the rotary regulatory body to the second angular position where the first inlet orifice is aligned to face the gas inlet, in the second axial position the distal end section of the elongate stop element does not extend beyond the distal end of the elongate passage to interact with the radially extending projection that is coupled to the drive shaft thereby permitting the regulatory body to be rotated to the third angular position. 7. A gas cooking appliance according to claim 6, wherein the first type of gas is natural gas and the second type of gas is liquid petroleum gas. 8. A gas cooking appliance according to claim 6, wherein the distal end section of the elongate stop element comprises a threaded section, the elongate passage comprising an unthreaded proximal section and a threaded distal section, the elongate stop element being in the first axial position when the threaded section of the elongate stop element is threaded through the threaded distal section of the elongate passage. 9. A gas cooking appliance according to claim 8, wherein the unthreaded proximal section of the elongate passage has a length sufficient to prevent the proximal end section of the elongate stop element from protruding from the housing when the elongate stop element is in the second axial position. 10. A gas cooking appliance according to claim 6, wherein the valve body comprises a main body and a cover, the housing being a part of the cover.
