Abstract

A fuel inlet assembly is provided for receiving fuel from a fuel-dispensing nozzle. The fuel inlet assembly has a filler pipe and a restrictor secured to the filler pipe. The restrictor has a diametrical opening. The assembly also has a protrusion that is attached to the restrictor and extends at an angle across a portion of the diametrical opening below the restrictor. The protrusion is made of an electrically conductive material and is sized, shaped, and positioned so as to contact the fuel-dispensing nozzle when the nozzle is inserted into the diametrical opening, thereby creating an electrical ground path between the nozzle and the fuel inlet assembly.

Claims (14)

1. A fuel inlet assembly for receiving fuel from a fuel-dispensing nozzle, the fuel inlet assembly comprising:

a filler pipe;

a restrictor secured to the filler pipe, the restrictor having a diametrical opening; and

a protrusion rigidly attached to the restrictor and extending at an angle across a portion of the diametrical opening below the restrictor;

wherein the protrusion is made of an electrically conductive, substantially rigid material and is sized, shaped, and positioned so as to without substantially deflecting contact the fuel-dispensing nozzle when the nozzle is inserted into the diametrical opening, thereby creating an electrical ground path between the nozzle and the fuel inlet assembly.

2. The fuel inlet assembly of claim 1 , wherein the protrusion aligns the centerline of the fuel-dispensing nozzle with the centerline of the fuel pipe as the operator inserts the nozzle through the diametrical opening.

3. The fuel inlet assembly of claim 1 , wherein the protrusion extends at an angle across the diametrical opening so as to narrow the path through the diametrical opening at increasing depths below the diametrical opening.

4. The fuel inlet assembly of claim 1 , wherein the restrictor and the protrusion are each made of a steel and are joined together by welding.

5. The fuel inlet assembly of claim 1 , wherein the restrictor and the protrusion are each made of a steel and are joined together by metal forming.

6. The fuel inlet assembly of claim 1 , wherein the restrictor and the protrusion are unitarily formed from a steel.

7. The fuel inlet assembly of claim 1 , wherein the restrictor is secured to the inside of the filler pipe by welding.

8. The fuel inlet assembly of claim 1 , wherein the restrictor is secured to the inside of the filler pipe by crimping.

9. The fuel inlet assembly of claim 1 , wherein the restrictor is a cylindrical can having an open top.

10. The fuel inlet assembly of claim 1 , wherein the restrictor is a disc having a plurality of notches around its perimeter to assist in non-rotatably securing the disc to the inside of the filler pipe.
