Abstract
A water mixing valve has an axially shiftable bottom pressed by water pressure against the valve seat disk in a housing for the assembly which allows the assembly to be inserted as a unit into the valve. The openings in the bottom have constrictions against which tubular seals press to provide the axial force which prevents a gap from forming between the bottom and the valve seat disk.
