ABSTRACT:
The invention comprises a mixing valve assembly with a cold and hot water inlet, a mixing chamber, and a mixed water outlet, wherein the mixed water temperature is adjustable by rotation of the actuator, and wherein a constant water flow can be set by axial depression of the actuator. More reliable operation is achieved, along with simplifications in manufacture and installation, by having on the assembly a locking device for the actuator, so constructed that when the actuator is depressed it is held by the locking device in the new position but is released when again depressed.
