Abstract: A gas burner with multiple rings of flames, suitable for mounting on a top plate of a cooking appliance in particular for household use. The top plate extends substantially in a plate plane. The gas burner includes a central burner having a ring of peripheral flames and at least one annular burner having at least one ring of peripheral flames. The annular burner surrounds the central burner. The gas burner also includes a burner body suitable for attachment to the top plate. The burner body includes at least a first gas inlet communicating with a first gas injector situated facing a first convergent-divergent pipe forming a Venturi tube. The first pipe has an axis substantially parallel to said plate plane. The first pipe extends over at least the greater portion of a transverse extension of the burner body. The first pipe is, at its end opposite to the first gas injector, in communication with a shaft substantially perpendicular to the axis of the first pipe.
