制御装置。[Claims for Utility Model Registration] An annular member for forming a short-circuit magnetic path made of a magnetic material is sandwiched between mutually opposing axial end portions, and the annular members are arranged on the same axis, and the excitation current is applied to each of them individually. two excitation coils which are given a A first valve having a relatively small-diameter jet that can sit on a valve seat surface formed at an open end around a main fuel passage having a large-diameter jet and communicate with the main fuel passage. a valve body; and a second valve body capable of seating on a valve seat surface formed at an open end of the small-diameter jet, the first valve body being connected to one of the two armatures; and the second valve body is connected to the other, and when only one of the two excitation coils is excited, only the armature on the side to which the second valve body is connected is attracted, and both of the two coils are excited. The fuel passage control device for a carburetor is characterized in that the two armatures are then sucked together.
