器。In a supercharged engine, a diaphragm device 21 is disposed in the auxiliary fuel passages 10, 12° 20 leading from the fuel float chamber 8 to the intake passage 6, and the diaphragm device 21 is arranged in a pressure chamber 16 and a fuel chamber 18 separated by a diaphragm 14. The pressure chamber 16 communicates with the intake passage 3 downstream of the throttle valve 7, and the fuel chamber 18 has one end connected to the float via a one-way valve 11 that prevents backflow of fuel to the fuel float chamber 8 side. The diaphragm 14 is connected to the fuel chamber 8 and the other end thereof is connected to a fuel passage 20 that opens to the intake passage 6 via a one-way valve 19 that prevents backflow of fuel to the fuel chamber 18 side.
is caused by the negative pressure and positive pressure generated in the intake passage 3 downstream of the throttle valve 7 from the intermediate position to the pressure chamber 16 side and the fuel chamber 18.
A carburetor for a supercharged engine that can be moved to both sides.
