Dual flush activation

1. A flush valve assembly comprising:

a housing mountable to a valve body having diaphragm valve disposed therein with a stem extended downwardly therefrom;

a handle pivotally mounted to the housing and engagable with the stem via a plunger;

the plunger having an outer end for engaging the handle, an inner end for engaging the stem, and a shank therebetween, the plunger being axially slidable through a passage in a bushing, the bushing positioned between the handle and the valve;

the passage in the bushing comprising a first axis and a second axis, the axes in substantially the same vertical plane and intersecting at a point, the point of intersection being a pivot point of the plunger;

wherein actuation of the handle in a first direction moves the plunger axially along the first axis and actuation of the handle in a second direction moves the plunger axially along the second axis.

2. The flush valve assembly of claim 1 , wherein the passage has a circular cross-section at the pivot point.

3. The flush valve assembly of claim 1 , wherein the passage exhibits an oval cross-section at an end opposite the pivot point.

4. The flush valve assembly of claim 1 , wherein an inner end of the plunger comprises a plunger tip.

5. The flush valve assembly of claim 1 , wherein the pivot point is positioned at substantially the inner end of the passage.

6. The flush valve assembly of claim 1 , wherein the pivot point is positioned at substantially the outer end of the passage.

7. The flush valve of claim 1 , wherein the first axis is substantially horizontal.

8. The flush valve of claim 7 , further comprising a third axis, wherein the second axis and third axis are tilted in opposite directions from the first horizontal axis.

9. A handle assembly for using with a flush valve, the handle assembly comprising:

a handle assembly housing comprising a handle, a plunger and a bushing all at least partially disposed therein;

the handle pivotally mounted within the housing and engagable with the plunger;

the plunger having an outer end for engaging the handle, an inner end, and a shank positioned therebetween and the plunger being axially slidable through a passage in the bushing, the bushing positioned opposite the handle within the housing;

the passage comprising a first axis and a second axis in substantially the same vertical plane and which intersect, the point of intersection positioned substantially at the inner end of the passage being a pivot point of the plunger;

wherein actuation of the handle in a first direction moves the plunger axially along the first axis and actuation of the handle in a second direction moves the plunger axially along the second axis.

10. The handle assembly of claim 9 , wherein the passage has a circular cross-section at the pivot point.

11. The handle assembly of claim 9 , wherein the passage exhibits an oval cross-section at an end opposite the pivot point.

12. The handle of claim 9 , wherein the first axis is substantially horizontal.

13. The handle of claim 12 , further comprising a third axis, wherein the second axis and third axis are tilted in opposite directions from the first horizontal axis.

14. The handle assembly of claim 9 , wherein an outer end of the plunger comprise a head having a diameter substantially larger than the diameter of the plunger.

15. The handle assembly of claim 14 , wherein the head comprises a flattened conical shape, the apex of the cone being nearest the handle.

16. The handle assembly of claim 14 , wherein the head comprises an inverted flattened conical shape, the apex of the inverted cone being farthest from the handle.

17. A handle assembly comprising:

a handle assembly housing comprising a handle, a plunger and a bushing all at least partially disposed therein;

the plunger having an outer end for engaging the handle, an inner end configured to be engagable with a valve stem sleeve, and a shank positioned therebetween, the plunger being axially slidable through a passage in the bushing, the bushing positioned opposite the handle within the housing;

the passage comprising a first axis and a second axis in substantially the same vertical plane and which intersect, the point of intersection being substantial at the outer end of the passage and being a pivot point of the plunger;

wherein actuation of the handle in a first direction moves the plunger axially along the first axis and actuation of the handle in a second direction moves the plunger axially along the second axis.

18. The handle of claim 17 , wherein the first axis is substantially horizontal.

19. The flush valve of claim 18 , further comprising a third axis, wherein the second axis and third axis are tilted in opposite directions from the first horizontal axis.

20. A handle assembly comprising:

a housing mountable to a valve body, the valve body having a diaphragm valve disposed therein with a sleeve extended therefrom;

a handle pivotally mounted to the housing and engagable with the valve via a plunger;

the plunger having an outer end for engaging the handle, an inner end for engaging the sleeve, and a shank positioned therebetween, the plunger being axially slidable through a bore in a bushing, the bushing positioned opposite the handle within the housing;

the bore comprising a horizontal axis, first tilted axis and a second tilted axis all in substantially the same vertical plane and which intersect, the point of intersection being a pivot point of the plunger;

wherein actuation of the handle in a first direction moves the plunger axially along the first tilted axis and actuation of the handle in a second direction moves the plunger axially along the second tilted axis and the plunger is positioned along the horizontal axis when not being actuated.

21. The handle assembly of claim 20 , wherein the passage has a circular cross-section at the pivot point.

22. The flush valve assembly of claim 20 , wherein the passage exhibits an oval cross-section at an end opposite the pivot point.
