Abstract

A vehicle fuel delivery apparatus, having: a surge chamber configured to store fuel; a fuel filter distally positioned with respect to and connected to the chamber; and a fuel level sender positioned between the filter and surge chamber.

First claim

We claim:

1. A fuel delivery module for arrangement in a fuel container of a vehicle, the module, comprising:
a surge chamber for storing fuel;
a fuel pump for conveying the fuel from the surge chamber to a fuel consumer;
a fuel filter through which the fuel flows;
wherein the fuel filter is received in a substantially cylindrical filter housing arranged separately from the surge chamber;

a first connecting rod mechanically linking an outer wall of the surge chamber to the filter housing;
a second connecting rod mechanically linking the outer wall of the surge chamber to the filter housing;
a transverse member connected to a flat end of the filter housing and to filter-side ends of the first and second connecting rods, thereby providing an opening between the filter housing and the surge chamber when the fuel delivery module is assembled; and
a fuel level sender pivotally attached to the outer wall of the surge chamber having a float retained by a swiveling arm,
wherein the swiveling arm is configured to swivel at least to a position in which the float is arranged between the filter housing and the surge chamber, via a swivel path between the first and second connecting rods such that the float traverses the opening between the filter housing and the surge chamber responsive to changes in fuel level.

2. The fuel delivery module of claim 1 , wherein the filter housing is arranged in a laterally distal position with respect to the surge chamber.

3. The fuel delivery module of claim 2 , wherein the first and second connecting rods are pivotally attached to the outer wall of the surge chamber.

4. The fuel delivery module of claim 3 , wherein the swiveling arm is configured to swivel at least to a position in which the float is arranged between the filter housing and the surge chamber when the fuel delivery module is in a final installed position in the fuel container.

5. The fuel delivery module of claim 4 , wherein the fuel pump is arranged in the surge chamber.

6. The fuel delivery module of claim 5 , further comprising:
a flange arranged above the surge chamber and configured for fastening the surge chamber to an upper wall of the fuel container.

7. The fuel delivery module of claim 1 , wherein the first and second connecting rods are pivotally attached to the outer wall of the surge chamber.

8. A vehicle fuel delivery apparatus, comprising:
a surge chamber configured to store fuel;
a fuel filter distally positioned with respect to and connected to the surge chamber and in a filter housing;
first and second connecting rods mechanically linking an outer wall of the surge chamber to the filter housing;
a transverse member connected to the filter housing and to filter-side ends of the first and second connecting rods, thereby providing an opening between the filter housing and the surge chamber when the vehicle fuel delivery apparatus is assembled; and
a fuel level sender positioned between the fuel filter and surge chamber when the vehicle fuel delivery apparatus is in a final installed position in a vehicle fuel container, the fuel level sender pivotally attached to the outer wall of the surge chamber having a float retained by a swiveling arm, wherein the swiveling arm is configured to swivel at least to a position in which the float is arranged between the filter housing and the surge chamber, via a swivel path between the first and second connecting rods such that the float traverses the opening between the filter housing and the surge chamber responsive to changes in fuel level.

9. The vehicle fuel delivery apparatus of claim 8 , wherein the fuel level sender includes a sender configured to read high-level and low-level fuel levels.

10. The vehicle fuel delivery apparatus of claim 9 , wherein the fuel level sender includes the float.

11. The vehicle fuel delivery apparatus of claim 10 , further comprising:
a bracket connecting the surge chamber and fuel filter comprising the first connecting rod mechanically linking the outer wall of the surge chamber to the filter housing, and the second connecting rod mechanically linking the outer wall of the surge chamber to the filter housing.

12. The vehicle fuel delivery apparatus of claim 11 , wherein the bracket is pivotally attached to the surge chamber to enable the fuel filter to be laterally disposed with respect to the surge chamber.

13. The vehicle fuel delivery apparatus of claim 12 , further comprising:
a pump linked to the surge chamber.

14. The vehicle fuel delivery apparatus of claim 13 , further comprising:
a sealing flange on the surge chamber configured to fasten the surge chamber to the fuel container.

15. The vehicle fuel delivery apparatus of claim 14 , wherein the pump is arranged in the surge chamber.
