At a thermostatic water mixing valve the cold water fed to an inlet (12) and the hot water fed to an inlet (14) by means of valves (32, 34; 32', 34') is fed to a mixin g chamber (36), whereat the valves are controlled by an expansion element (38). The expansio n element (38) is arranged within a spring cage (40), the inner contour of which being matched to the outer contour of the expansion element (38). Furthermore, a ring gap (99) an d a collar (95) are arranged in the mixing chamber in the zone where the cold water and the hot water come together. Soft sealing rings (32) inserted into the valve closing body (28) give protection against scalding when the cold water supply fails.
