Abstract
A fuel supply unit for a vehicle includes a fuel tank, a fuel pump for providing a fuel supply system of the vehicle with fuel introduced from the fuel tank via a strainer disposed therein, a fuel return pipe for returning surplus fuel from the fuel supply system to the fuel tank and a spongy fuel-adsorbing member disposed between the strainer end a tip of the fuel return pipe.
Claims20
A fuel supply unit for a vehicle, comprising:
- a fuel tank;
- a fuel pump for providing a fuel supply system of the vehicle with fuel introduced from said fuel tank via a strainer disposed therein;
- a fuel return pipe for returning surplus fuel from said fuel supply system to said fuel tank;
- and
- a spongy fuel-adsorbing member positioned on at least an upper surface of said strainer and being disposed between said strainer and a tip of said fuel return pipe, said spongy fuel-adsorbing member being made of a corrosion-resistant metal, porous and includes a plurality of minute pores for enabling separation of the return fuel into gases and liquid fuel and for protecting against a surge in the fuel caused by gases in the fuel, wherein fuel adsorbed by said spongy fuel-adsorbing member is retained to slowly move to said strainer for stabilizing ripples caused on the surface of the fuel around the fuel-adsorbing member and for stabilizing fuel supplied to said strainer.

A fuel supply unit for a vehicle, comprising:
- a fuel tank;
- a strainer having at least an upper surface and a lower surface and being disposed within said fuel tank;
- a fuel pump for pumping fuel contained within the fuel tank, the fuel being introduced to said fuel pump from said fuel tank via said strainer disposed therein;
- a fuel return pipe having a first end and a second end for returning surplus fuel from said fuel supply system to said fuel tank;
- a spongy fuel-adsorbing member positioned on at least said upper surface of said strainer and being disposed between said strainer and the second end of said fuel return pipe, said spongy fuel-adsorbing member being porous and elastic and includes a plurality of minute pores for enabling separation of the return fuel into gases and liquid fuel and for protecting against a surge in the fuel caused by gases in the fuel, fuel being adsorbed by said spongy fuel-adsorbing member is retained to slowly move to said strainer for stabilizing ripples caused on the surface of the fuel around the fuel-adsorbing member and for stabilizing fuel supplied to said strainer;
- and
- a partition disposed in said fuel tank adjacent to said lower surface of said strainer and including side members for covering predefined areas of side portions and a top portion of said spongy fuel-adsorbing member.
