Saddle tank fuel delivery system
View Patent ↗The present invention provides a fuel delivery system for a saddle fuel tank wherein a fuel pump and a jet pump are positioned within an active side of the tank. The jet pump is directly driven by the fuel pump to draw the fuel from a passive side of the tank to the active side of the tank.
1. A fuel delivery assembly for use in a saddle fuel tank that stores fuel for a vehicle having an engine, the saddle fuel tank having a first side and a second side, said fuel delivery assembly comprising:
a fuel pump adapted to be positioned in the first side of said saddle fuel tank, said fuel pump having an Inlet and an outlet;
a diverter having an inlet in fluid communication with said fuel pump cutlet, a first outlet being in fluid communication with the engine, and a second outlet;
a jet pump adapted to be positioned in the first side of said saddle a tank, said jet pump having a first inlet adapted to be in fluid communication with said diverter second outlet, said jet pump also having a second inlet adapted to be in fluid communication with the second side of the saddle fuel tank, and said diverter having an outlet adapted to be in fluid communication with the first side of the saddle fuel tank; and
a single crossover tube adapted to communicate between the first side and the second side, wherein the crossover tube has an inlet in the second side of the saddle fuel tank and an outlet in fluid communication with said second inlet of said jet pump;
wherein said diverter is a T-shaped valve; and
wherein said jet pump is T-shaped and includes an internally positioned nozzle.
2. A fuel delivery assembly for use in a saddle fuel tank that stores fuel for a vehicle having an engine, the saddle fuel tank having a first side and a second side, said fuel delivery assembly comprising:
a fuel pump adapted to be positioned in the first side of said saddle fuel tank, said fuel pump having an inlet and an outlet;
a diverter having an inlet in fluid communication with said fuel pump outlet, a first outlet being in fluid communication with the engine, and a second outlet;
a jet pump adapted to be positioned in the first side of said saddle tank, said jet pump having a first inlet adapted to be in fluid communication with said diverter second outlet, said jet pump also having a second inlet adapted to be in fluid communication with the second side of the saddle fuel tank, and said diverter having an outlet adapted to be in fluid communication with the first side of the saddle fuel tank; and
a single crossover tube adapted to communicate between the first side and the second side, wherein the crossover tube has an inlet in the second side of the saddle fuel tank and an outlet in fluid communication with said second inlet of said jet pump;
wherein said diverter is a parallel pressure relief valve.
3. The fuel delivery assembly of claim 2 wherein said parallel pressure relief valve includes a check valve, a pressure relief valve arranged parallel to the check valve, an inlet in fluid communication with said fuel pump, a first outlet positioned downstream from said check valve and in fluid communication with the engine, and a second outlet exiting into the first side of the saddle fuel tank.
4. The fuel delivery assembly of claim 2 wherein said jet pump is T-shaped.
5. The fuel delivery assembly of claim 2 wherein said jet pump includes an internally positioned nozzle.
6. The fuel delivery assembly of claim 5 wherein said first inlet of said jet pump has an upstream portion and a downstream portion and said downstream portion includes said nozzle.
7. The fuel delivery assembly of claim 2 wherein said single crossover tube is within the saddle tank.
8. A fuel delivery assembly for use in a saddle fuel tank that stores fuel for a vehicle having an engine, the saddle fuel tank having a first side and a second side, said fuel delivery assembly comprising:
a fuel pump adapted to be positioned in the first side of said saddle fuel tank, said fuel pump having an inlet and an outlet;
a diverter having an inlet in fluid communication with said fuel pump outlet, a first outlet being in fluid communication with the engine, and a second outlet;
a jet pump adapted to be positioned in the first side of said saddle tank, said jet pump having a first inlet adapted to be in fluid communication with said diverter second outlet, said jet pump also having a second inlet adapted to be in fluid communication with the second side of the saddle fuel tank, and said diverter having an outlet adapted to be in fluid communication with the first side of the saddle fuel tank; and
a single crossover tube adapted to communicate between the first side and the second side, wherein the crossover tube has an inlet in the second side of the saddle fuel tank and an outlet in fluid communication with said second inlet of said jet pump;
wherein said diverter and said jet pump are an integrated component.
9. The fuel delivery assembly of claim 8 wherein said integrated component has a first inlet in fluid communication with said fuel pump outlet, a second inlet in fluid communication with said cross-over tube, a first outlet in fluid communication with the engine and a second outlet exiting into the first side of the tank.
10. The fuel delivery assembly of claim 9 wherein said integrated component defines an internal nozzle.
11. The fuel delivery assembly of claim 10 wherein said nozzle is located upstream of said second inlet of said integrated component.
12. The fuel delivery assembly of claim 10 wherein said nozzle is located downstream of said first outlet.
