Abstract

Improvements to carburettors for internal combustion engines of the type comprising downstream to upstream in their intake duct, a main throttle member actuated by the driver and a main venturi in which a secondary venturi is placed, smaller than the main venturi and coaxial with the main venturi, in which an outlet port of the main fuel nozzle system is made and a calibrated diaphragm fixed the secondary venturi removably upstream of the outlet port, characterized in that the diaphragm (16) empties into the secondary venturi (6) at a point located, in the air path, upstream of the outlet hole (14), a diaphragm that offers the air a passage section smaller than the smaller passage section offered by the secondary venturi downstream of the diaphragm.
