。[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. A variable vent lily in which the auxiliary fuel nozzle is formed by a piston valve that is displaced by negative pressure in the intake passage, an auxiliary fuel nozzle is opened in the outer vent lily, and auxiliary fuel is supplied from the auxiliary fuel nozzle to the outer vent lily in accordance with the displacement of the piston valve. In the type carburetor, a negative pressure chamber is provided for operating the piston valve, an atmosphere introduction passage whose one end is opened to the atmosphere is communicated with the negative pressure chamber, and a valve that opens the atmosphere introduction passage when the manifold negative pressure is large. A variable ventilator type carburetor characterized by being equipped with a yume switching valve. (2) The vacuum switching valve includes a diaphragm, an atmospheric chamber that is defined by the diaphragm and forms a route for the atmospheric introduction passage, a negative pressure chamber that introduces the negative pressure of the manifold, and a negative pressure chamber that introduces the negative pressure of the manifold, and the diaphragm is connected to the atmospheric chamber side. The variable ventilee type carburetor according to claim 1, which is a registered utility model, and comprises a spring that presses the diaphragm toward the atmosphere chamber, and a valve body that is attached to the atmosphere chamber side of the diaphragm and opens and closes the atmosphere introduction passage.
