The cooking appliance (1) having a control panel ( 2) is equipped with one or more gas flow (Q) regulating valves, wherein the rotary regulator organ (6) is provided with various peripheral through holes (16-19). The control knob (9) being interchangeable for fitting to the actuating shaft (7), is chosen from the two units available, one and the other permitting different angular limit positions (A2, A3) for the supply of a constant minimum gas flow Qmin, through one of two successive holes (18, 19) calibrated each one for a different type of gas NG or LPG, one or the other hole being superimposed to a valve inlet duct (4) at a different angular position A2, A3. An integral lug (14) on the control knob (9) running into a slide groove (20) in the control panel (2), establishes a first rotation stop A2.

What is claimed is: 1. Gas cooking appliance adapted for a supply with different types of gaseous fuel, natural gas (NG) or liquefied petroleum gas (LPG), equipped with one or more regulating valves (3) of the rotary regulator organ (6) type, comprising: a regulating valve (3) having a valve body (
What is claimed is: 1. Gas cooking appliance adapted for a supply with different types of gaseous fuel, natural gas (NG) or liquefied petroleum gas (LPG), equipped with one or more regulating valves (3) of the rotary regulator organ (6) type, comprising: a regulating valve (3) having a valve body (3 a) provided with a housing for the regulator organ (6), an inlet conduit (4) and an outlet conduit (5), and an actuating shaft (7) mounted salient from a control panel (2) on the cooking appliance (1), wherein a regulated gas flow "Q" is directed towards the outlet conduit (5) to a cooking appliance burner adapted to one of these types of gas, said rotary regulator organ (6) provided with a revolution peripheral surface and various peripheral through openings ( 16-19) for the passage of a regulated flow "Q" to a central chamber (8) in communication with said outlet conduit (5), the passage openings being superimposed in alignment with said inlet conduit (4), successively in function of a respective angular position of the regulator organ (6), wherein, starting from an initial valve closed "OFF" position (A1,A1/A2,A2,A3), in accordance with each one of said angular positions (A1,A1/A2,A 2,A3) of the regulating organ (5), three different possible flows, a constant maximum flow "Qmax", a constant minimum flow "Qmin", and an intermediate flow "Qint" between them, are supplied to the outlet conduit (5), in function of the area of the through opening (16-19) facing the inlet conduit (4), said actuating shaft (7) provided with a means ( 13) for guiding the angular travel (A3) of the regulator organ (6), interacting with a rotation stop means (12a) in the valve body (12a), an interchangeable control knob (9) fitted at the free end of the actuating shaft (7), provided with a integral means ( 14) for guiding said angular travel (A2) and interacting with a rotation stop means (20) in the control panel (2) of the appliance, wherein said rotation stop means (12a) in the valve body (12a) determines an angular position A2 of the regulating organ (6), for the supply of a first flow Qmin through one of said openings (18), calibrated for one type of gas (NG), and said rotation stop means (20) in the control panel ( 2) determines an angular position A3 successive to the prior position A2, for the supply of a second flow Qmin for another type of gas (LPG), through a second calibrated opening (19) spaced apart from the former. 2. The gas cooking appliance according to claim 1, wherein the regulator organ (6) comprises a series of said various peripheral openings (16-19), aligned in the rotational direction for the supply of said Qmax, Qint and first and second Qmin flows of either of the N or LP gas types, being of these two successive holes (18, 19) calibrated for the supply of the respective constant Qmin, and positioned angularly at the end of a respective travel A2, A3, and said guide means (14) on the control knob (9) comprises an integral shoulder or lug (14) on a base (9a) facing the control panel (2), which presents a circular slide groove (20) establishing the travel extension A2, and one control knob (9) fitted to the actuating shaft (7) is chosen between two different units available, with or without said lug (14) depending in either case on the type of gas, NG or LPG, supplied to the cooking appliance (1 ). 3. The gas cooking appliance according to claim 1, wherein said guide means on the control knob (9) comprises a shoulder or lug (14) on its base (9a) facing the control panel (2), which presents a circular slide groove (20) establishing the rotation stop at a first angular position A2, and said guide means (13) on the actuating shaft (7) comprises a radial pin (13) interacting with a recess (12a) in the valve cover (12), which establishes the rotation stop at a second angular position A3.
