Abstract

PURPOSE: To prevent an accumulation of air bubble in the auxiliary path, by providing an auxiliary fuel path made open and close with an output signal of exhaust composition detector in the fuel path of the carburetor, and providing a main jet near around this auxiliary path.
CONSTITUTION: Drawing a shows as example as conventionally used, and a float chamber 11 is linked to an intake path 2 through a main jet 10, a fuel path 8 and a main nozzle 5. Further an area between the float chamber 11 and the fuel path 8 is linked by a sub and auxiliary fuel path 13, 12 through a valve 21, and the valve 21 is feed-back controlled in accordance with the exhaust component. In this device, an air bubble has been easily accumulated in the interior by a reason with a long auxiliary fuel path 12 provided to the main jet 10. To remove a trouble in the above, a branch path 28, linking the sub and auxiliary path 12, 13, as shown in the drawing b, is constructed before the valve 21, and in the branch path 28 is provided the main jet 10. And on the subpath 13, is arranged an air bubble relief port 14 made open and close by the valve 21.
