Abstract
For enhanced stability of fuel supply to an engine, a fuel tank system of a vehicle has a first and a second fuel tank for storing fuel. The tanks are interconnected by a connecting pipe with a one-way valve disposed in the connecting pipe such that fuel can flow from a filling tank to an engine supply tank but not in the reverse direction.
Claims6
A fuel tank system of a vehicle, comprising:
- a first fuel tank for storing a fuel;
- a second fuel tank for storing the fuel;
- a connecting pipe for interconnecting the first and second fuel tanks;
- and
- a one-way valve disposed within the connecting pipe.
2 more elements
A fuel tank system for a vehicle, comprising:
- at least two fuel tanks;
- at least one connecting pipe interconnecting said at least two fuel tanks such that said fuel tanks are maintained in fluid communication, wherein said at least one connecting pipe interconnects said fuel tanks toward a bottom of said fuel tanks;
- a fuel feeder pipe connected to a first fuel tank of said at least two fuel tanks;
- a fuel induction pipe disposed in a second fuel tank of said at least two fuel tanks and coupled with a fuel pump for withdrawing fuel from the second fuel tank and pumping fuel to an engine;
- and
- a one way valve disposed within said at least one connecting pipe for regulating flow of fuel from the first fuel tank towards the second fuel tank and restricting flow in the direction from the second fuel tank towards the first fuel tank, wherein said one way valve includes a tubular body, a plate hingedly attached to the tubular body, and a biasing member disposed to provide a closing force on the plate such that the plate is urged against the tubular body.
3 more elements
A fuel supply system for a vehicle, comprising:
- a vehicle having an engine;
- a fuel supply system, wherein said fuel supply system includes;
- at least a first and a second fuel tank;
- at least one interconnecting line between said fuel tanks for fluidly connecting said fuel tanks;
- a one way valve positioned within said interconnecting line such that fuel can flow from said second fuel tank to said first fuel tank but not from said first fuel tank to said second fuel tank;
- a fuel pump and a fuel pick up line associated with said first fuel tank;
- and
- a fuel feeder line associated with said second fuel tank for receiving fuel into said fuel supply system from an outside fuel supply source.
