Abstract

An inline dispersal valve that can be used with or without a base. One embodiment includes a rotatable member that is rotatable from a fluid stream obstructing condition to an out-of-the-way condition to prevent fluid diversion into the dispersal valve. Another embodiment includes a lever handle for quickly setting the amount of fluid being diverted into the inline dispersal valve. Another embodiment includes an indicator that can be viewed from a position above the inline dispersal valve. Another embodiment includes a cap that can be secured or removed without the aid of tools. Another embodiment includes a clip that allows one to disassemble the inline dispersal valve for servicing. Another embodiment includes a dispensing valve that can be reversed and still properly divert fluid into a dispersant chamber. Another embodiment includes an inline dispersal valve with a bleed valve positioned to allow one to bring the air volume in the dispersant chamber to the proper level.

First claim

We claim:

1. A dispenser for controlling a fluid flow therein comprising:
a housing having a dispersing chamber;
a fluid port in the housing;
a rotatable member having a fluid deflecting surface with a radius of curvature substantially the same as a radius of curvature of a fluid conduit of an inline dispersal valve to form a portion of the fluid conduit of the dispenser when the fluid deflecting surface is displaced out of a lumen located in the housing for opening and closing the fluid port with the fluid port located below the dispersing chamber; and
a fluid port indicator having a window for observing a number in a set of dial numbers corresponding to a specific size of an opening of the fluid port with the fluid port indicator visible from a position above the housing to enable a user to select a fluid port setting from the position above the housing by rotation of the rotatable member.

2. The dispenser of claim 1 wherein the fluid port comprises a fluid port of variable sizes in the housing.

3. The dispenser of claim 1 wherein the rotatable member includes a set of circumferential seals located thereon to prevent fluid leakage therepast.

4. The dispenser of claim 1 wherein the rotatable member includes a lever handle to enable the user to rotate the rotatable member to open and close the fluid port.

5. The dispenser of claim 1 wherein the rotatable member and the housing comprises a polymer plastic.

6. The dispenser of claim 1 wherein the rotatable member includes at least one fluid channel to direct fluid into a chamber of the housing and at least one fluid channel to direct fluid from the chamber into a conduit.

7. The dispenser of claim 1 wherein the dispersant chamber supports a canister containing a dispersant therein.

8. The dispenser of claim 1 wherein the dispersant chamber contains a dispersant therein.

9. The dispenser of claim 8 including a fluid conduit in the housing for fluid flow therethrough.

10. A dispenser for controlling a fluid flow therein comprising:
a housing having a chamber;
a fluid port in the housing;
a rotatable member located in the housing for opening and closing the fluid port;
a fluid port indicator, the fluid port indicator visible from a position above the housing to enable a user to select a fluid port setting from the position above the housing by rotation of the rotatable member;
a dispenser cover including a cap and a cover housing rotatable with respect to the cap; and
a set of radial protruding handles extending from the cover housing to enable a user to bring the cap into and out of engagement by rotating of the cover housing wherein the protruding handles comprises ergonomic handles having a shape that conforms to the natural curvature of the user's hand and the rotatable member includes a fluid deflecting surface displaceable into a lumen in a conduit to thereby divert at least a portion of a fluid flowing in the conduit to flow through the chamber before returning to the conduit, the fluid deflecting surface displaceable out of the lumen in the conduit to form a portion of the conduit to direct fluid through the conduit without diverting fluid into the chamber in the dispenser to thereby create a no flow condition through the chamber.

11. The dispenser of claim 10 wherein the rotatable member includes a barrier for preventing fluids from exiting the chamber when the fluid deflecting surface is displaceable out of the lumen in the conduit.

12. The dispenser of claim 10 wherein the fluid deflecting surface of the rotatable member extends transverse to a flow direction through the conduit.

13. The dispenser of claim 10 wherein the fluid deflecting surface of the rotatable member has an axis of rotation extending transverse to a flow direction through the conduit.

14. The dispenser of claim 10 wherein the fluid deflecting surface of the rotatable member has a radius of curvature substantially the same as a radius of curvature of the conduit to thereby establish an uninhibited flow condition therethrough.

15. The dispenser of claim 10 wherein an axis of rotation of the fluid deflecting surface of the rotatable member is spaced from a central flow axis through the conduit.

16. The dispenser of claim 10 wherein the rotatable member includes a lever handle with the lever handle comprising a pointer to indicate a rotational position of the fluid deflecting surface.

17. The dispenser of claim 10 wherein the rotatable member includes a guard located on a cylindrical surface of the rotatable member and surrounding the fluid deflecting surface for restricting and confining the movement of the fluids directed from the fluid stream into the chamber to an inlet of the chamber.
