Abstract

A toilet fill valve device may function as a restrictor to reduce water flow, or as a regulator to cap water flow beneath a certain limit depending upon its orientation. If composed of a rigid material, the device functions as a restrictor to decrease water flow. If composed of a soft, flexible or compressible/expandable material, the device functions as a regulator as its walls expand to partially block fluid passageways when water pressure fills up a void within the device. The device includes a spiraled outer surface to provide a tortuous path for water to travel so as to reduce noise. The dual functionality of a regulator or restrictor may also be accomplished with the orientation of the device. Methods for manufacturing and using a toilet fill valve control device are also provided.

Claims (46)

1 . A toilet fill valve control device, comprising:

a hollow body including a closed end and an open end, the hollow body comprising an expandable sidewall; and

a tortuous outer surface included in the hollow body, the tortuous outer surface comprising a plurality of flow paths.

2 . The device of claim 1 , wherein the sidewall is composed of an elastomeric material.

3 . The device of claim 1 , wherein the outer surface comprises a spiraled surface.

4 . The device of claim 3 , wherein the plurality of flow paths comprising dual a plurality of spiraled flow paths.

5 . The device of claim 1 , further comprising a fill valve having a vertical conduit with an inner surface, and wherein the hollow body is configured to slidingly abut the inner surface of the vertical conduit.

6 . The device of claim 5 , wherein:

the vertical conduit defines a fluid passageway;

the hollow body disposed within the vertical conduit defines an upstream section and a downstream section of the fluid passageway; and

wherein the hollow body is configured to be disposed within the vertical conduit in either a first position where the open end faces the upstream section or a second position wherein closed end faces the upstream section.

7 . A toilet fill valve control device, comprising:

a fill valve having a vertical conduit that includes an inner surface and defines a fluid passageway;

a hollow flexible body disposed in the vertical conduit and configured to abut the inner surface of the vertical conduit so as to define an upstream section and a downstream section of the fluid passageway, the hollow body comprising a closed end, an open end and a sidewall; and

wherein the hollow flexible body is reversible such that it may be oriented in a first position where the open end faces the upstream section, and a second position wherein the closed end faces the upstream section.

8 . The device of claim 7 , wherein the sidewall comprises a plurality of flow paths.

9 . The device of claim 7 , further comprising means for providing a tortuous flow path.

10 . The device of claim 9 , wherein the means for providing a tortuous flow path comprises a spiraled outer surface formed on the hollow body.

11 . The device of claim 7 , wherein the hollow body is composed of an expandable material.

12 . The device of claim 7 , wherein the hollow body caps a flow rate of fluid in the fill valve in the first position.

13 . The device of claim 7 , wherein the hollow body is slidingly disposed in the vertical conduit.

14 . A method of manufacturing a fill valve, comprising:

providing a fill valve with a vertical conduit that defines an inner diameter;

providing a flexible hollow body having a closed end, an open end and an outer diameter that is substantially similar to the inner diameter of vertical conduit; and

disposing the hollow body in the vertical conduit in one of two possible positions.

15 . The method of claim 14 , wherein disposing the hollow body in the vertical conduit in one of two possible positions comprises:

dividing a passageway of the vertical conduit into an upstream section and a downstream section; and

facing the open end of the hollow body toward the upstream section.

16 . The method of claim 14 , wherein disposing the hollow body in the vertical conduit in one of two possible positions comprises:

dividing a passageway of the vertical conduit into an upstream section and a downstream section; and

facing the closed end of the hollow body toward the upstream section.

17 . The method of claim 14 , wherein providing the flexible hollow body having a closed end, an open end and an outer diameter that is substantially similar to the inner diameter of vertical conduit comprises:

forming the flexible hollow body with a spiraled outer surface.

18 . A method for controlling fluid flow in a toilet fill valve, comprising:

directing fluid through a vertical conduit of a fill valve;

disposing a flexible hollow body in the vertical conduit so as to divide the vertical conduit into an upstream section and a downstream section;

capping the flow rate of the fluid in the fill valve by orienting the flexible hollow body in a first position; and

reducing a flow rate of the fluid in the fill valve by orienting the flexible hollow body in a second position.

19 . The method of claim 18 , wherein disposing a flexible hollow body in the vertical conduit comprises:

disposing in the vertical conduit an expandable fluid control device having an open end and a closed end.

20 . The method of claim 19 , wherein reducing the flow rate of the fluid in the fill valve by orienting the flexible hollow body in the second position comprises:

facing the closed end of the hollow body toward the upstream section.

21 . The method of claim 19 , wherein capping the flow rate of the fluid in the fill valve by orienting the flexible hollow body in the first position comprises:

facing the open end of the hollow body toward the upstream section.

22 . The method of claim 23 , wherein capping the flow rate of the fluid in the fill valve by orienting the flexible hollow body in the first position comprises:

filling the hollow body with the fluid so as to expand a sidewall of the hollow body against an inner surface of the vertical conduit.
