Patent ID: 8490812

Claim:
A fuel tank, comprising: a fuel tank body having an interior for storing fuel; a filler neck for filling the fuel into the interior of the fuel tank body, the filler neck having an inlet external of the fuel tank body and an outlet communicating with the interior of said fuel tank body; and a recirculation device having a tube element completely disposed inside of said fuel tank body, said tube element having a funnel-shaped inlet and an outlet lower than the inlet, the inlet of the tube element being disposed substantially coaxial with the outlet of the filler neck and spaced apart from said filler neck, such that said inlet of said tube element opens directly into the interior of the fuel tank body at a position external of the filler neck, with said inlet of said tube element being positioned in the fuel tank for fuel stored in the fuel tank body not to reach the inlet even when the fuel tank body is filled with the fuel, and said tube element having a constriction configured to function as a Venturi nozzle that generates a suction for sucking fuel vapor from the interior of the fuel tank body into said funnel-shaped inlet as fuel being filled into the fuel tank through said filler neck flows as a free jet into said inlet of said tube element.
