ABSTRACT:
The gas flow regulating valve (1) is adapted to one cooking burner amongst the several on a cooking hob. The regulating valve member (7) is cylindrical-shaped and coupled to a step motor “M”, which controls the axial displacement “X” thereof through a fixed closure member (8), over successive positions (P0–P6) effecting the regulation of an outlet gas flow “Q” between the OFF and a minimum flow Qmin. The regulating member (7) is provided with at least one elongated superficial recess (9,9′) communicating the inlet side (3a) with the outlet side (3b) of the gas chamber, a regulating surface opening (9,11) provided with a surface groove (11) adjacent to said superficial recess (9) towards the outlet side (3b), in the form of a variable passage area (A,H) for the regulation of a intermediate flow Qgra, and at least one gas through-flow conduit (12) in permanent communication with the outlet side (3b) for a calibrated flow Qmin.
