気化器。[Scope of Claim for Utility Model Registration] (1) It has an inner vent turret and an outer vent lily in the middle of the intake passage, the main nozzle for injecting the main fuel is opened in the inner vent lily, and one part of the wall of the outer vent lily is opened. The part is formed by a piston valve that is displaced by negative pressure in the intake passage, and a power nozzle is opened in the outer vent lily.
In a variable ventilator type carburetor that supplies power fuel from a power nozzle to an outer ventilary according to the displacement of a piston valve, the piston valve is provided with a jet needle insertion hole having a diameter larger than that of the jet needle. A variable ventilee type carburetor, characterized in that a projecting portion large enough to not pass through the hole is attached to the upper portion, a spring is interposed between the projecting portion and the piston valve, and a jet needle is attached to the piston valve. (2) forming a groove on the side surface of the piston valve having a width narrower than the diameter of the jet needle leading to the hole;
The variable ventilator type according to claim 1 of the registered utility model claim, characterized in that the jet needle is formed with a small diameter portion that is narrower than the width of the groove so that the jet needle can reach the hole through the groove. vaporizer. (3) A guide is formed in the middle of the nozzle pipe, a guide for slidably holding the jet needle is attached near the opening at the tip of the nozzle pipe, and the throat position of the nozzle pipe and the guide position are A variable ventilee type carburetor according to claim 1, characterized in that a power fuel injection port is provided between the carburetors.
