Adjustable flush system
View Patent ↗A flush valve assembly having a handle assembly positioning bushing for spacing a handle assembly within an opening of the flush valve assembly. The handle assembly positioning bushing having an eccentric opening for receiving the handle such that rotation of the handle assembly positioning bushing with regard to the flush valve assembly body alters the height of the handle assembly and, thus, the volume of water passing through the flush valve assembly during a flush cycle.
1. A flush valve assembly comprising;
a flush valve assembly body having an inlet, an outlet and a handle opening and further including a valve member disposed therein with a stem extended downwardly therefrom such that it is adjacent the handle opening;
a handle assembly including 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 there between, the plunger being axially slidable through a passage in a bushing, the bushing securable to a handle assembly socket for retaining the handle and plunger;
a handle assembly positioning bushing disposable within the handle opening, the handle assembly bushing have an inner passage eccentrically positioned within the handle assembly bushing and adapted to receive the handle assembly, the handle assembly bushing configured to rotate within the handle opening wherein the height of the handle assembly relative to the valve stem is altered as the handle assembly bushing is rotated
wherein the handle assembly positioning bushing is completely disposed within the handle opening.
2. The flush valve assembly of claim 1 , wherein the handle assembly positioning bushing includes an indicia positioned such that the indicia, a handle opening central longitudinal axis, and a interior passage central longitudinal axis define a plane.
3. The flush valve assembly of claim 2 , wherein the indicia is a hollowed portion of the handle assembly positioning bushing.
4. The flush valve assembly of claim 3 , wherein the hollowed portion is a hole on an annular face of the handle assembly and is configured to receive a tool for rotating the handle assembly positioning bushing within the flush valve assembly body.
5. The flush valve assembly of claim 1 , wherein the valve member is a diaphragm type flushometer valve.
6. The flush valve assembly of claim 1 , wherein venting time of the flush valve assembly is altered in accordance with sine law with an angle defined by the bushing passage central longitudinal axis and a horizontal plane passing through the central longitudinal axis of the handle opening.
7. A flush valve assembly comprising;
a flush valve assembly body having an inlet, an outlet and a handle opening and further including a valve member disposed therein with a stem extended downwardly therefrom such that it is adjacent the handle opening;
a handle assembly including 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 there between, the plunger being axially slidable through a passage in a bushing, the bushing securable to a handle assembly socket for retaining the handle and plunger;
a handle assembly positioning bushing disposable within the handle opening, the handle assembly bushing have an inner passage eccentrically positioned within the handle assembly bushing and adapted to receive the handle assembly, the handle assembly bushing configured to rotate within the handle opening wherein the height of the handle assembly relative to the valve stem is altered as the handle assembly bushing is rotated
wherein the handle assembly positioning bushing is completely disposed within the handle opening;
an annular groove circumscribed about an exterior of the handle assembly positioning bushing, the annular groove configured to receive a o-ring, the o-ring seated within the annular groove to sealingly engage the flush valve body.
8. The flush valve of claim 7 , wherein the handle assembly positioning bushing is completely disposed within the handle opening.
9. The flush valve assembly of claim 7 , wherein the handle assembly positioning bushing includes an indicia positioned such that the indicia, a handle opening central longitudinal axis, and a interior passage central longitudinal axis define a plane.
10. The flush valve assembly of claim 9 , wherein the indicia is a hollowed portion of the handle assembly positioning bushing.
11. The flush valve assembly of claim 10 , wherein the hollowed portion is a hole on an annular face of the handle assembly and is configured to receive a tool for rotating the handle assembly positioning bushing within the flush valve assembly body.
12. The flush valve assembly of claim 7 , wherein the valve member is a diaphragm type flushometer valve.
