Gas burner, as particularly intended for use in cooktops for residential food cooking applications, comprising a lower body (1), a top cap (2) closing said lower body on top, two coaxial flame rings (3,4) having the same diameter, but extending at two different heights, a single gas injector (5), a single Venturi tube (8), and a single expansion chamber (10) for the gas issuing from said single Venturi tube, said chamber being adapted to supply said two flame rings of the burner.
The burner further comprises a first cylindrically-shaped hollow annular member (6) adapted to be applied vertically upon said lower body, and a second substantially planar hollow annular member (7), which is adapted to be applied upon said first annular member (6) and support said cap.
The lower flame ring is supplied with gas from said expansion chamber via a plurality of ducts, which are substantially arranged within said first cylindrically shaped annular member.
Said two flame rings are provided with gas outlet ports having sensibly similar cross-section areas. |
