Abstract
PURPOSE: To prevent excessive concentration of air-fuel mixture by providing an auxiliary diaphragm device to make the opening degree larger when high negative pressure at the time of deceleration is worked on a choke valve, in a carburetor equipped with a choke opener.
CONSTITUTION: A main diaphragm 8 as an opener is connected to a choke valve 3, and opening of the choke valve 3 is done in response to negative pressure downstream of a throttle valve 2 which is let in through a main negative pressure duct 20. Besides, an auxiliary diaphragm 10 is connected through an auxiliary rod 11 to the main diaphragm 8, and the same negative pressure is let through an auxiliary negative pressure duct 21 into its negative pressure chamber 19. And the auxiliary diaphragm 10 is set to move under high negative pressure at the time of deceleration, and the choke valve 3 is slightly opened by moving to the right at the time of deceleration.
