Claims

[Scope of utility model registration request]

An acceleration auxiliary fuel passage 7 opening to the intake passage 3 and this passage 7
It includes an on-off valve 9 that opens and closes the on-off valve 9, and a control section 10 that stops the on-off valve 9 from opening and closing.
A first diaphragm 11 that drives the first diaphragm 11, a second diaphragm 16 that adjusts the spring load of the valve closing spring 14 acting on the first diaphragm 11, and a suction pipe negative pressure introduced into the first diaphragm 11. a first negative pressure chamber 12 for moving the second diaphragm 16 in the direction of closing the valve; and a second negative pressure chamber 17 into which suction pipe negative pressure is introduced to move the second diaphragm 16 in the direction of increasing the spring load; The first negative pressure chamber 12 is a carburetor acceleration auxiliary device which is communicated with the adjustment chamber 18 on the opposite side of the first diaphragm IT through a throttle passage 23.
