<p>1. Gas admixing nozzle for carburettors of combustion engines, with a ring conduit (16) lying approximately in the intake plane (17) and discharging in the carburettor, for the selective supply of gaseous fuels instead of the liquid fuel, the ring conduit (16) being arranged concentrically to an opening (2), which can be sealed by means of a throttling device operated by the intake vacuum in the higher speed range, characterized in that a covering disk (1), featuring the opening (2) sealed by the throttling device, is arranged with an axial spacing in front of the intake plane (17) and essentially parallel to same, and that an annular gap (24) of adequate size for the intake of air in the lower speed range is provided in the direction of flow in speed range is provided in the direction of flow in front of the ring conduit between the latter and the opening (2), and that the disk (1) extends from the ring conduit (16) with an axial nozzle (13) of a smaller diameter than a subsequent air intake nozzle (14) into the latter up to immediately in front of the gas outlet (15).</p> |
