Dispensing systems

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.

         20 . 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.   
     
     
         21 . The dispenser cartridge of  claim 20  wherein the end cap has a set of fluid ports therein with the rib centrally positioned with respect to the set of fluid ports. 
     
     
         22 .- 27 . (canceled) 
     
     
         28 . The dispenser cartridge of  claim 21  wherein the rib extends outward from a socket end cap of the dispenser cartridge. 
     
     
         29 . The dispenser cartridge of  claim 21  wherein the rib has a rectangular shape with a top surface extending transverse to a central axis through the dispenser cartridge. 
     
     
         30 . 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.   
     
     
         31 . The inline dispenser of  claim 30  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 to impede or block flow through the fluid port in the second end cap in one mode and to allow fluid flow through the second end cap in a second mode. 
     
     
         32 . The inline dispenser of  claim 30  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. 
     
     
         33 . The inline dispenser of  claim 30  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. 
     
     
         34 . The inline dispenser of  claim 30  wherein a sidewall of the inline dispenser socket extends parallel to a central axis of the inline dispenser. 
     
     
         35 . The inline dispenser of  claim 30  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. 
     
     
         36 . The inline dispenser of  claim 35  wherein the dispensing cartridge is frictionally mated to said inline dispenser socket with a deactivator cam on the dispensing cartridge in engagement with the flow limiter in the end cap when the dispensing cartridge is located in the chamber. 
     
     
         37 . The inline dispenser of  claim 31  wherein a further dispenser cartridge includes a further deactivator cam for engaging the second flow limiter. 
     
     
         38 .- 56 . (canceled)
