Abstract

An improper fuel nozzle insertion-inhibiting assembly may include a cover having a nozzle inlet barrier door pivotally secured to the cover. The cover may include a safety-release groove that is configured to separate the cover into separate pieces upon exertion of sufficient force. A main body is secured to the cover and configured to connect to a fuel fill pipe. The main body may include a nozzle outlet barrier door pivotally secured to the main body. A debris filter may be secured to one or both of the cover and/or the main body. The debris filter is configured to prevent debris from passing into an internal chamber. A pivot-restricting member(s) may be secured within the internal chamber. The pivot-restricting member(s) is configured to prevent one or both of the nozzle inlet barrier door and the nozzle outlet barrier door from over-pivoting. At least one seal member may be configured to sealingly engage at least portions of the fuel fill pipe, the cover, and the main body.

First claim

The invention claimed is:

1. An improper fuel nozzle insertion-inhibiting assembly configured to prevent an improper fuel-dispensing device from dispensing fuel into a fuel fill line of a vehicle, the improper fuel nozzle insertion-inhibiting assembly comprising:
a cover including a pinless nozzle inlet barrier door pivotally secured to the cover, and a safety-release groove that is configured to separate the cover into separate pieces upon exertion of sufficient force, wherein the pinless nozzle inlet barrier door includes an integral first seal;
a main body secured to the cover and configured to connect to a fuel fill pipe, wherein the main body includes a pinless nozzle outlet barrier door pivotally secured to the main body, wherein the pinless nozzle outlet barrier door includes an integral second seal, wherein at least a first portion of the main body securely connects to at least a second portion the cover;
a debris filter secured to and disposed within and around a circumferential wall of one or both of the cover and the main body, wherein the debris filter is configured to prevent debris from passing into an internal chamber defined by one or both of the cover and the main body;
at least one pivot-restricting member secured within and extending into the internal chamber, wherein the at least one pivot-restricting member is configured to prevent one or both of the nozzle inlet barrier door and the nozzle outlet barrier door from over-pivoting; and
a seal member that is configured to sealingly engage at least portions of the fuel fill pipe, the cover, and the main body.

2. The improper fuel nozzle insertion-inhibiting assembly of claim 1 , wherein the debris filter comprises a tortuous path that is configured to allow pressurized fluid within the internal chamber to pass out of the internal chamber, and wherein the tortuous path is configured to prevent the debris from passing into the internal chamber.

3. The improper fuel nozzle insertion-inhibiting assembly of claim 1 , wherein the at least one pivot-restricting member comprises one or more of a stud, latch, beam, block, or rib extending into the internal chamber.

4. The improper fuel nozzle insertion-inhibiting assembly of claim 1 , wherein the at least a first portion of the main body comprises an outwardly-extending annular connector, and wherein the at least a second portion of the cover comprises a circumferential groove formed on an inner wall, and wherein the circumferential groove snapably retains the annular connector.

5. The improper fuel nozzle insertion-inhibiting assembly of claim 1 , wherein the safety-release groove extends around a circumference of an outer surface of the cover.

6. The improper fuel nozzle insertion-inhibiting assembly of claim 1 , wherein the cover securely connects to the fuel fill pipe and at least one other fuel fill pipe formed of a different material and having a different shape than the fuel fill pipe.

7. An improper fuel nozzle insertion-inhibiting assembly configured to prevent an improper fuel-dispensing device from dispensing fuel into a fuel fill line of a vehicle, the improper fuel nozzle insertion-inhibiting assembly comprising:
a cover including a nozzle inlet barrier door pivotally secured to the cover, wherein the cover includes a safety-release groove that is configured to separate the cover into separate pieces upon exertion of sufficient force;
a main body secured to the cover and configured to connect to a fuel fill pipe, wherein the main body includes a nozzle outlet barrier door pivotally secured to the main body; and
a debris filter secured to and disposed within and around a circumferential wall of one or both of the cover and the main body, wherein the debris filter is configured to prevent debris from passing into an internal chamber defined by one or both of the cover and the main body.

8. The improper fuel nozzle insertion-inhibiting assembly of claim 7 , wherein the debris filter comprises a tortuous path that is configured to allow pressurized fluid within the internal chamber to pass out of the internal chamber, and wherein the tortuous path is configured to prevent the debris from passing into the internal chamber.

9. The improper fuel nozzle insertion-inhibiting assembly of claim 7 , further comprising at least one pivot-restricting member secured within and extending into the internal chamber, wherein the at least one pivot-restricting member is configured to prevent one or both of the nozzle inlet barrier door and the nozzle outlet barrier door from over-pivoting.

10. The improper fuel nozzle insertion-inhibiting assembly of claim 9 , wherein the at least one pivot-restricting member comprises one or more of a stud, latch, beam, block, or rib extending into the internal chamber.

11. The improper fuel nozzle insertion-inhibiting assembly of claim 7 , further comprising at least one seal member that is configured to sealingly engage at least portions of the fuel fill pipe, the cover, and the main body.

12. The improper fuel nozzle insertion-inhibiting assembly of claim 7 , wherein the main body comprises an outwardly-extending annular connector, and wherein the cover comprises a circumferential groove formed on an inner wall, and wherein the circumferential groove snapably retains the annular connector.

13. The improper fuel nozzle insertion-inhibiting assembly of claim 7 , wherein the safety-release groove extends around a circumference of an outer surface of the cover.

14. The improper fuel nozzle insertion-inhibiting assembly of claim 7 , wherein the cover securely connects to the fuel fill pipe and at least one other fuel fill pipe formed of a different material and having a different shape than the fuel fill pipe.

15. The improper fuel nozzle insertion-inhibiting assembly of claim 7 , wherein the debris filter includes a passage that extends through the cover and into the internal chamber, wherein a filtering medium is positioned within the passage.

16. An improper fuel nozzle insertion-inhibiting assembly configured to prevent an improper fuel-dispensing device from dispensing fuel into a fuel fill line of a vehicle, the improper fuel nozzle insertion-inhibiting assembly comprising:
a cover including a nozzle inlet barrier door pivotally secured to the cover;
a main body secured to the cover and configured to connect to a fuel fill pipe, wherein the main body includes a nozzle outlet barrier door pivotally secured to the main body; and
a debris filter secured to and disposed within and around a circumferential wall of one or both of the cover and the main body, wherein the debris filter is configured to prevent debris from passing into an internal chamber defined by one or both of the cover and the main body.

17. The improper fuel nozzle insertion-inhibiting assembly of claim 16 , wherein the debris filter comprises a tortuous path that is configured to allow pressurized fluid within the internal chamber to pass out of the internal chamber, and wherein the tortuous path is configured to prevent the debris from passing into the internal chamber.

18. The improper fuel nozzle insertion-inhibiting assembly of claim 16 , further comprising at least one pivot-restricting member secured within and extending into the internal chamber, wherein the at least one pivot-restricting member is configured to prevent one or both of the nozzle inlet barrier door and the nozzle outlet barrier door from over-pivoting.

19. The improper fuel nozzle insertion-inhibiting assembly of claim 16 , further comprising at least one seal memb
