Abstract
PURPOSE: To perform proper feeding of accelerating fuel during the driving time in such a way that an auxiliary accelerating pump in series with a main accelerating pump of a carburetor in order to work this auxiliary pump only at the time of cooling off the engine.
CONSTITUTION: A main accelerating pump 12 is installed between an air intake passage 62 and a float chamber 10, accelerating fuel is led through a fuel passsage 50 and an accelerating nozzle 14 into the air intake passage 62. And an auxiliary accelerating pump 16 having a diaphragm 38 is allocated on the fuel passage 50, at the same time, a negative pressure 18 in this pump 16 is conducted in such a way that it can be change over through a thermosensitive changeover valve 54 from negative pressure delay valves 56, 60 to the atmosphere or an air intake pipe. Then when the engine is cooled off, the negative pressure chamber 18 is conducted with the air intake pipe, and the auxiliary pump 16 is put into operation.
