を特徴とする二連コンパウンド気化器。 A primary side intake cylinder equipped with a choke valve, a secondary side intake cylinder equipped with a secondary side throttle valve, a diaphragm drive device that is operated by negative pressure to control the secondary side throttle valve, and each of the intake cylinders. The compound vaporizer is a two-way compound vaporizer consisting of a negative pressure passage that introduces the negative pressure of the bench valve into the diaphragm chamber of the diaphragm drive device, and is opened by the pressure downstream of the chiyoke valve when the chiyoke valve is inactive, and is opened at low speed under the action of the chiyoke valve. A dual compound vaporizer characterized in that a switching valve is provided in the negative pressure passage, which is closed during operation and opened during high-speed operation under the action of a chiyoke valve.
