Abstract (en)

A fuel supply device for carburetors of the type which provides a branch passageway (17) communicating with a fuel passageway between a fuel metering jet (4) and a connection of a fuel passageway (6) with a negative pressure passageway (9) and a float chamber (5), places a diaphragm type enriched valve (32), in the middle of the branch passageway, controlled in accordance with the variation of the negative pressure generated on the downstream side of a solenoid valve or a throttle valve controlled by signals issued from various sensors detecting an operating condition of an engine and controls a fuel flow rate so that the level of a fuel column to be formed in the negative pressure passageway for intake flow rate detection communicating with the fuel passageway is kept constant, in order to enable a fuel supply to be positively performed with respect to any transient state of engine operation.
