Abstract

A system for limiting the flow from a dispensing valve when a dispensing cartridge is replaced with the system including a dispenser cartridge with a cam and a water socket with a flow limiter therein that is activeable in response to the position of the dispenser cartridge in the dispensing valve and operable in response to an upstream fluid pressure in the dispensing valve.

First claim

We claim:

1. A mateable dispenser cartridge having a central axis for insertion into a dispensing valve comprising:
an elongated housing having a dispersant compartment therein;
a first socket located on a first end of said housing;
a first end cap located in said first socket with said first end cap having a fluid port;
a second socket located on the first end of said housing;
a second end cap located in said second socket with said second end cap having a fluid port; and
a deactivator cam located in said first socket, said deactivator cam extending axially outward from said first end cap with said deactivator having a cam face.

2. The mateable dispenser cartridge of claim 1 wherein the fluid port in the first end cap comprises a set of fluid ports therein with the deactivator cam centrally positioned with respect to the set of fluid ports.

3. In combination the mateable dispenser cartridge of claim 1 and a converter wherein one of the sockets on the dispensing cartridge has a sidewall in mating engagement with a sidewall of either a socket in the converter or a socket in the dispensing valve with said socket in the converter or said socket in the dispensing valve including a flow limiter.

4. The combination of claim 3 wherein the converter includes a further socket connectable to a further water socket of the dispensing valve.

5. The combination of claim 3 wherein the flow limiter includes a retaining head for axially restraining the flow limiter and a flange for obstructing flow when the flow limiter is in an active condition.

6. The combination of claim 5 wherein the flow limiter includes a split head for axially inserting the flow limiter into an opening in the first end cap through pinching the split head together before inserting the split head into the opening in the first end cap.

7. The combination of claim 3 wherein the deactivator cam has a cam face extending transverse to a central axis of the dispenser cartridge to thereby abut against an end of the flow limiter to maintain the flow limiter in a deactivated condition when the dispenser cartridge is in mating engagement with the socket in either the converter or the dispensing valve.

8. The combination of claim 7 wherein the deactivator cam extends axially outward from the end cap in the first socket with a height of said deactivator cam less than a height of a sidewall of the first socket, said deactivator cam positionally located with respect to the sidewall of the first socket and the flow limiter is similarly positionally located with respect to a socket sidewall in the converter or a socket sidewall in the dispensing valve so that when the dispensing cartridge is installed into either the converter or the dispensing valve the socket sidewall in either the converter or the socket sidewall in the dispensing valve are in mating engagement with the dispensing valve to thereby bring the deactivator cam into engagement with the flow limiter.

9. The combination of claim 1 and a further mateable dispenser cartridge where the further mateable dispenser cartridge has an annular shape with each of the dispenser cartridges having at least one socket for mating engagement with a socket in a converter or a dispensing valve.

10. A dispenser cartridge having a central axis for insertion into a dispensing valve comprising:
an annular housing having an annular chamber therein;
an outlet socket located on said housing for directing a fluid stream out of the annular chamber in said housing;
an inlet socket located on said housing for directing a fluid stream into the annular chamber in said housing;
an end cap on said inlet socket;
a rib located in said inlet socket, said rib extending axially outward from said end cap with said rib having a cam face for disengaging a flow limiter located upstream of the inlet socket when the inlet socket of the dispenser cartridge is engagement with a socket of either a converter or a socket of an inline dispersal valve.

11. The annular dispenser cartridge of claim 10 wherein the end cap has a set of fluid ports therein with the rib centrally positioned with respect to the set of fluid ports.

12. The dispenser cartridge of claim 10 wherein the rib has a height less than a sidewall of the inlet socket so that the sidewall of the inlet socket on the housing can engage a sidewall of a converter before the rib contacts a flow limiter in the converter.

13. The dispenser cartridge of claim 10 including a second dispenser cartridge nested within the dispenser cartridge with the second dispenser cartridge includes a rib.

14. The dispenser cartridge of claim 13 wherein the rib of the first dispenser cartridge and the rib of the second dispenser cartridge each includes a cam face for deactivating a flow limiter as the first dispenser cartridge and the second dispenser cartridge are inserted into an inline dispenser.

15. The dispenser cartridge of claim 13 wherein the cam face of the second dispenser extends in a direction normal to a central axis of the dispenser cartridge.

16. The dispenser cartridge of claim 10 wherein the rib is an integral portion of the housing of the dispenser cartridge.

17. The dispenser cartridge of claim 11 wherein the rib extends outward from a socket end cap of the dispenser cartridge.

18. The dispenser cartridge of claim 11 wherein the rib has a rectangular shape with a top surface extending transverse to a central axis through the dispenser cartridge.

19. An inline dispenser comprising:
a housing having a chamber;
an inlet on said housing for directing water into the chamber;
an outlet on said housing for directing water out of the chamber;
an inline dispenser socket located in said housing with said inline dispenser socket engageable with a dispensing cartridge socket, said inline dispenser socket having an end cap with a fluid port therein; and
a flow limiter located in said end cap, said flow limiter displaceable in response to insertion or removal of a dispenser cartridge from the inline dispenser to thereby impede or block flow through the end cap in one mode and to permit fluid flow through the end cap in a second mode.

20. The inline dispenser of claim 19 including a second flow limiter located on a second end cap, said second flow limiter displaceable in response to insertion or removal of a further dispenser cartridge from the inline dispenser.

21. The inline dispenser of claim 19 wherein the flow limiter includes a stem having a retaining head on one end and a flange on the opposite end with the stem axially displaceable with respect to the end cap when the dispensing cartridge is inserted into the dispenser.

22. The inline dispenser of claim 19 wherein the flow limiter includes a flange located on an upstream side of the end cap with said flange blocking or impeding flow through the end cap when the flange is proximate an upstream side of the end cap.

23. The inline dispenser of claim 19 wherein a sidewall of the inline dispenser socket extends parallel to a central axis of the inline dispenser.

24. The inline dispenser of claim 19 including a dispensing cartridge located in the chamber, said dispensing cartridge having a deactivator cam for rendering the flow limiter inoperative when the dispensing cartridge is present in the chamber.

25. The inline dispenser of claim 24 wherein the dispensing cartridge is frictionally mated to said inline dispenser socket with a deactivat
