Abstract

A fuel dispensing nozzle incorporating a lever assembly that enables a user to more easily and controllably dispense fuel through the nozzle. More particularly, the nozzle has a fuel flow path running through it, with an automatic fuel flow shutoff mechanism and a spring loaded valve assembly with an associated valve stem positioned along the fuel flow path above a lever assembly that regulates the flow of fuel through the nozzle. The lever assembly has a latch plate pivotally connected between the shutoff mechanism and a handle, such that the handle engages the valve stem to provide the user with more leverage to open the valve assembly than is available in conventional nozzle configurations.

Claims

1. An automatic fuel dispensing nozzle comprising a body, a fuel flow path within the body, an inlet at a first end of the fuel flow path, an outlet at a second end of the fuel flow path, a valve assembly positioned along the fuel flow path and being movable between a closed position in which fuel flow through the nozzle is prevented and an opened position in which fuel flows through the nozzle, an axially movable valve stem that engages said valve to move the valve between its opened and closed positions, an automatic fuel flow shutoff mechanism, and a lever assembly engaged with the valve stem, the lever assembly comprising:

a. a latch plate having a first end and a second end, said first end being pivotally connected to the shutoff mechanism; and

b. a handle having a first end and a second end, the first end being pivotally connected to the latch plate between the first and second ends of said latch plate, the handle engaging the valve stem between the first and second ends of said handle.

2. The nozzle of claim 1, wherein the handle comprises a grip portion and a link, the handle link engaging the valve stem and having a first end and a second end, the first end of the handle link being pivotally connected to the grip portion and the second end of the handle link being pivotally connected to the latch plate.

3. The nozzle of claim 2, wherein the handle link engages the valve stem between the first and second ends of said link.

4. The nozzle of claim 2, wherein the handle further comprises a central portion, said handle central portion being positioned between the grip portion and the link, the first end of said handle link being pivotally connected to said handle central portion.

5. The nozzle of claim 1, further comprising a lock plate, said lock plate being pivotally connected to the handle at a first end of said lock plate, and capable of releasably engaging the latch plate at a second end of said lock plate.

6. The nozzle of claim 5, further comprising a guard, said guard being connected to the nozzle body and positioned about the lever assembly, the second end of the latch plate being capable of engaging the guard.

7. The nozzle of claim 6, wherein the top of the latch plate comprises at least one ridge, said ridge being oriented on the latch plate to positionally restrain the lock plate upon engagement of the lock plate with the latch plate to maintain the handle in a raised position.

8. The nozzle of claim 1, wherein the valve assembly is spring loaded and downwardly biased against the handle.

9. The nozzle of claim 1, further comprising means for vapor recovery.

10. A lever assembly for an automatic fuel dispensing nozzle, the nozzle comprising a body, a fuel flow path within the body, an inlet at a first end of the fuel flow path, an outlet at a second end of the fuel flow path, a valve assembly positioned along the fuel flow path and being movable between a closed position in which fuel flow through the nozzle is prevented and an opened position in which fuel flows through the nozzle;

and an axially movable valve stem that engages said valve to move the valve between its opened and closed positions;

said lever assembly engaging said valve stem to move said valve from its closed to opened positions;

the lever assembly comprising;

a. a latch plate having a first end and a second end, said first end being operatively pivotally connected to the shutoff mechanism; and

b. a handle having a first end and a second end, the first end being pivotally connected to the latch plate between the first and second ends of said latch plate, the handle engaging the valve stem between the first and second ends of said handle.

11. The lever assembly of claim 10, wherein the handle comprises a grip portion and a link, the handle link engaging the valve stem and having a first end and a second end, the link first end being pivotally connected to the grip and the link second end being pivotally connected to the latch plate.

12. The lever assembly of claim 11, wherein the handle link engages the valve stem between the first and second ends of said link.

13. The lever assembly of claim 11, wherein the handle further comprises a central portion, said handle central portion being positioned between the grip portion and the handle link, the link first end being pivotally connected to said handle central portion.

14. The lever assembly of claim 10, further comprising a lock plate, said lock plate being pivotally connected to the handle and capable of releasably engaging the latch plate.

15. The lever assembly of claim 14, wherein the nozzle further comprises a guard, said guard being connected to the nozzle body and positioned about the lever assembly, the second end of the latch plate being capable of engaging the guard.

16. The lever assembly of claim 15, wherein the top of the latch plate has a ridge, said ridge being oriented on the latch plate to positionally restrain the lock plate upon engagement of the lock plate with the latch plate.

17. The lever assembly of claim 16, wherein the valve assembly is spring loaded and downwardly biased against the handle.

18. An automatic fuel dispensing nozzle comprising a body, a fuel flow path within the body, an inlet at a first end of the fuel flow path, an outlet at a second end of the fuel flow path, a valve assembly positioned along the fuel flow path and being movable between a closed position in which fuel flow through the nozzle is prevented and an opened position in which fuel flows through the nozzle, an axially movable valve stem that engages said valve to move the valve between its opened and closed positions, and a lever assembly engaged with the valve stem, the lever assembly comprising:

a. a latch plate having a first end and a second end, said first end being operatively pivotally connected to the shutoff mechanism; and

b. a handle having a grip portion and a link portion, the link being pivotally connected at one end to the latch plate between the first and second ends of said latch plate;

the grip portion being pivotally connected to a second end of the link; and

the link engaging the valve stem between the first and second ends of said link.

19. The nozzle of claim 18, further comprising vapor recovery means.

20. A conventional fuel dispensing nozzle comprising a body, a fuel flow path within the body, an inlet at a first end of the fuel flow path, an outlet at a second end of the fuel flow path, a valve assembly positioned along the fuel flow path and being movable between a closed position during which fuel flow through the nozzle is prevented, and then opens to a position in which fuel flows through the nozzle, a movable valve stem that engages said valve to move the valve between its opened and closed positions, and a lever assembly engaged with the valve stem, a handle guard connecting with the nozzle body, and locating the lever assembly within the same, the lever assembly comprising;

a. a latch plate having a first end and a second end, said first end being operatively pivotally connected to the handle guard; and

b. a handle having a grip portion and a link portion, the link being pivotally connected at one end to one of the latch plate and handle guard, the grip portion of the handle being pivotally connected to a second end of the link; and

the link engaging the valve stem between the first and second ends of said link, to open the valve assembly upon raising of the handle of the nozzle during dispensing.
