Abstract
PURPOSE: To facilitate attaching and detaching of a needle by allowing the jet needle of a variable-venturi type carburetor to be held by a needle supporting collar and the member which is engaged with the collar fixed on the needle.
CONSTITUTION: The movable valve 14 supported onto a shaft 15 and driven by an actuator 42 shifts in an intake passage 4, and thus the area of a venturi 17 is varied. The jet needle 25 engaged with the movable valve 14 advances and retreats in a needle jet 18, the thus the fuel amount is controlled. At the end part of an airhorn 3, a control chamber 21 is formed, where a needle pressing spring 34 and a needle supporting collar 31 are installed. In the movable valve 14, a projected engagement part 29 is formed, which is always engaged with the collar 27 set on the needle 25, and thus the needle 25 is supported.
