In a valve cartridge for a plumbing fixture that comprises a cartridge housing that has one connection opening, each for the inflowing cold and hot water and at least one discharge opening for the outflowing water, a mixing valve with a control element/operating handle for selecting the mixing ratio of cold and hot water, and a rotary valve with a control element/operating handle for selecting the flow rate of water through the valve cartridge, wherein the mixing valve and the rotary valve and/or the control element of the mixing valve and the control element of the rotary valve are arranged in series on an axis of the cartridge housing. The control element of the rotary valve can take the form of a hollow cylinder that is coaxial to the control element of the mixing valve and is attached to the rotary valve in a rotationally fixed manner.

A fluid delivery system (A) is generally directed to allowing fluid sources or other fluid delivery components to be reused with multiple fluid targets (), and includes at least one fluid source () fluidly interconnectable with at least one sterilization zone () and at least one fluid target (). This sterilization zone () could include one or more sterilization systems that attempt to neutralize contaminants entering the fluid delivery system (A) by a backflow from the fluid target (). One such sterilization system (A-D) includes a container (-) and a flush system () for sterilizing the container (-) between uses. Another sterilization system () includes a flowpath () exposed to an output of an energy source () capable of destroying contaminants. Yet another sterilization system could include a sterilizing substance () that engages and moves along an interior surface () of a housing () to treat contamination thereon.
