Abstract

PURPOSE: To hold a needle and a jet in linear configuration and improve the accuracy of fuel injection, by supporting the jet needle which interlocks with the movable valve of a variable-venturi type carburetor, shiftably in a needle supporting member.
CONSTITUTION: A movable valve 15 which is supported onto a shaft 15 and driven by an actuator 30 shifts in an intake passage 4, and varies area of a venturi 17. In the control chamber 21 formed at the end of an airhorn 3, a needle pressing spring 28 and a needle supportig member 23 are installed, and support by pressing the end of the jet needle 24 which advances and retreats in a needle jet 18. A projected engagement member 26 is intalled, in the movable valve 14, and always engaged with the collar 25 fixed to the needle 24, whereby the needle 24 and the jet 18 are always held in linear configuration.
