とを特徴とする２連気化器。[Scope of Claim for Utility Model Registration] The first throttle valve, the second throttle valve, and the first throttle valve are operated by the negative pressure generated in the bench lily portion during high output operation with a predetermined opening degree or more. A dual carburetor equipped with a negative pressure actuator that controls the opening and closing of a valve, comprising: a diaphragm on which a ventilator negative pressure acts on the negative pressure actuator; and a back spring that biases the diaphragm in the closing direction of the second throttle valve. and an auxiliary spring made of a shape memory alloy which has a spring load smaller than that of the back spring and biases the diaphragm in the opening direction of the second throttle valve. A dual vaporizer characterized by having a memorized shape that is larger than the spring load when cold.
