Abstract

PURPOSE: To eliminate play of a needle and increase the accuracy of fuel injection by pressing the jet needle of a variable-venturi type carburetor by means of a pressing spring, allowing the jet needle to follow a movable valve.
CONSTITUTION: The movable valve 14 supported onto a shaft 15 and driven by an actuator 35 shifts in an intake passage 4, and the area of a venturi 17 is varied. A needle pressing spring 27 and a needle supporting member 22 are arranged, in the control chamber A formed at the end part of an airhorn 3, and support and press the end of a jet needle 23 which advances and retreats in a needle jet 18. A projected engagement member 25 is arranged, in the movable valve 14, and is engaged with the collar 24 fixed on the needle 23 and supports the needle 23. The needle 25 is always applied from a spring 27 with the force towards the jet 18.
