A carburettor for supplying gaseous fuels in internal combustion engines, comprises a main body (101, fig.1B) comprising an intake section (102, fig.1B), a first pressure reduction section (1, fig.2), a second pressure reduction section 2 connected to the first section (1), a supply section 3 connected to the second pressure reduction section 2, and a Venturi device (4, fig.5) connected to the supply section 3, wherein the Venturi (4) forms a central portion of the carburettor (100, fig.1B). The first pressure reduction section (1) and the supply section 3 extend on opposite sides of the Venturi device (4), the second supply section (2) being interposed between the first pressure reduction section (1) and the supply section 3 and wherein the supply section 3 further comprises an actuating device 6 that can allow passage of fuel through a third conduit 130 towards the third chamber 30 to enrich the fuel/air mix during engine starting. |
