water flow from hot and cold inlets to the outlet spout 22 alternatively one could select other commercial ceramic mixing valves such as the kerox model gn 40a which is advertised to be suitable for use with joystick control in any event the cartridge should be able to accept a conventional hot water inlet connection 26 and cold water inlet connection 28 and be connectible to a mixed water outlet tube 30 further the control disks or other structures of the valve should be suitable to be activated by pivoting or other movement of the stick lever 32 further in accordance with the present invention a joystick type faucet handle 34 is then mounted to stick lever 32 in this embodiment to permit relative axial movement there between a cover 42 is positioned between the joystick handle 34 and front 20 and a biasing element 38 in the form of a spring is positioned outside front 20 between joystick handle 34 and stick lever 32 biasing element 38 biases handle 34 outward and thus domed skirt 40 attached thereto against a corresponding recess in cover 42 biasing element 38 is shown as a coil spring however other biasing structures are possible such as leaf springs spring washers elastomeric materials and other resilient compressible elements such as a gas diaphragm there is also a gasket 44 between front 20 and cover 42 cover 42 also includes an approximately central aperture 46 through which extends at least part of domed skirt 40 other elements include o ring 48 collar 50 spring washer 52 and nut 54 nut 54 is threadably engaged with casing 56 to provide an outer limit for mixing valve cartridge 24 among other things and screws 58 fix cover 42 to casing 56 split nut 60.
