抑止装置。An expansion tank having an evaporated fuel inlet, a gaseous fuel outlet, and a liquid fuel drain port is installed between the fuel tank and the canister, and the evaporated fuel inlet of the expansion tank is connected to the fuel tank so that the evaporated fuel is generated in the fuel tank. The vaporized fuel can be introduced into the expansion tank, and the vaporized fuel inlet of the expansion tank is provided with a check valve that opens when the pressure exceeds a predetermined value, so that the pressure of the vaporized fuel in the fuel tank exceeds the predetermined value. When the evaporated fuel is released into the expansion tank while being adiabatically expanded, a part of it is liquefied. The fuel liquefied in the tank is returned to the tank, and the gaseous fuel outlet is connected to a canister so that the gaseous fuel not liquefied in the expansion tank is guided to the canister and adsorbed. , device for suppressing evaporated fuel from automobile fuel tanks.
