A gas burner (3) for food cooking appliances is described, which comprises a gas feeding duct (2), wherein a first sump (2A) and a second sump (2B) are connected to said duct (2) through at least one pair of nozzles (2C, 2D), the gas to be supplied to the gas burner (3) being mixed in said first (2A) and second (2B) sumps with primary air taken from above a cooking top (8), on which the gas burner (3) can be mounted, in order to create an air-gas mixture. The invention is mainly characterized in that the gas burner (3) comprises a pair of Venturi effect chambers (10) arranged on diametrically opposed sides with respect to a central axis (A) of the gas burner (3) and adapted to direct the flow of air-gas mixture towards said gas burner (3), each chamber (10) having a respective first axis (10A) inclined towards the central axis (A) of said gas burner (3), wherein said first axis (10A) of each chamber converges towards said central axis (A) at a point positioned above the gas burner (3). |
