Abstract
PURPOSE: To make possible to make air fuel ratio correpond to change of the atmospheric pressure by providing an orifice in a passage from an actuator to an air bleeder and providing a control valve which changes the opening area of the orifice corresponding to the atmospheric pressure.
CONSTITUTION: In an air supplying passage from an actuator for the main (not shown) to a variable air bleeder 13, an orifice 19 is provided, a needle 20 which faces the orifice 19 is connected with the center of a diaphragm 18 and a bellows 21 whose one end contacts with the inner surface of a venturi 13 while the other end contacts with the diaphragm 18 via a spring 17 is provided. When the main actuator opens and supplied air flows, the pressure difference between venturi negative pressure and the atmospheric pressure decreases, the bellows 21 contracts slightly, the needle 20 approaches the orifice 19 and decreases the quantity of supplied air, the air fuel ratio of gas mixture is therefore made thinner.
