Claims

[Scope of utility model registration request]

A float chamber of a vaporizer with an opening on the circumference above the normal oil level, a sub-tank with an opening on the top below the opening, and a connection between the circumferential opening of the float chamber and the top opening of the sub-tank. A passage that guides fuel to the sub-tank when the oil level in the float chamber rises, a fuel return passage that communicates the air chamber of the fuel tank sealed from the outside air with the bottom of the sub-tank, and a fuel return passage that branches off from the fuel return passage and has a tip. Provided in a passage open to the atmosphere, when the valve is opened, the air chamber of the fuel tank is communicated with the atmosphere, and when the valve is closed, the internal pressure of the fuel tank when the engine is stopped is turned into a negative pressure, and fuel is sucked from the sub-tank into the fuel tank. A fuel recovery device characterized by being equipped with a cock.
