Abstract
Improvements in carburettors for internal combustion engines, consisting, downstream to upstream in its intake duct, of a main throttle member actuated by the driver, of a venturi into which a main fuel dispenser system flows. powered by a constant level tank, and an auxiliary throttle (such as a start valve) suitable to be closed only when the engine is cold to increase the depression in the level of said system and, consequently, the flow of this, whose carburetor also consists of an enriching device that comprises a fuel circuit that starts from the constant level tank and empties into the intake duct through an injection hole located so that it flows from downstream to upstream auxiliary throttle member in the opening movement of the latter, this circuit being commanded by a shutter that is sensitive to the pressure prevailing in the intake duct downstream of its main throttle member and that interrupts or releases this circuit depending on whether the engine rotates with a weak or partial load or with a strong load, characterized in that the fuel circuit (12) is connected to the constant level tank (4) by means of a well (10) which is, on the one hand, connected to the tank (4) by a calibrated hole (11) located below the constant level (N) of this tank (4) and on the other hand, aerated by an air channel (26-28) that empties into the well (10) below this constant level (N).
