Abstract:
1. Burner for gas cookers, said burner comprising: at least one flame spreader and at least one corresponding lid adapted to define at least partially a transit chamber for a gas-primary air fuel mixture, said at least one flame spreader including, (i) at least a plurality of radial outlets obtained by through holes passing through the flame spreader and in fluidic communication with said transit chamber to feed a plurality of main flames with said fuel mixture, (ii) in combination with said at least one corresponding lid, at least one outflow port disposed above said plurality of radial outlets; to feed at least one pilot flame with said fuel mixture, said at least one outflow port being so shaped as to establish said at least one pilot flame in the direction towards said at least one plurality of radial outlets, and (iii) one or more inlets disposed above said plurality of radial outlets and in fluidic communication with said transit chamber, wherein said at least one flame spreader and at least one corresponding lid define at least one storage chamber for feeding said fuel mixture to said at least one pilot flame, said storage chamber being disposed intermediate of and in fluid communication with said at least one outflow port and said one or more inlets, said storage chamber being fed by said one or more inlets in fluidic communication with said transit chamber for the fuel mixture and said at least one storage chamber being so shaped as to allow a fuel mixture pressure drop sufficient to allow the storage of the fuel mixture in said storage chamber and the delivering of said fuel mixture with a substantially constant pressure at said at least one outflow port said storage chamber being disposed above the through holes passing through the flame spreader, wherein said at least one storage chamber and said at least one outflow port are defined by at least a portion of the lower peripheral surface of said at least one lid and by at least a portion of the an upper peripheral surface of said at least one flame spreader.
