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.

Sanitary mixing valve assembly

In order to achieve a fully automatic, electronic adjustment by means of a process for controlling a plumbing combination set with a multi-disc mixing valve for hot and cold water, whereby temperature is adjusted by making a comparison between the actual temperature of the mixing water and the target temperature of the mixing water, it is proposed that the actual mixing value be constantly measured and that a factor for the regulator of the appropriate mixing valve adjustment disc be derived from the target/actual divergence, and that at the same time the preselected flow of the mixture can be maintained at a constant level without measurement of the flow quantities, a correction factor being derived from the factor of the aforementioned adjustment disc for the factor of the flow adjustment disc regulator.

Plumbing mixing circuit control apparatus for a combination set

To simplify and improve the functioning of a plumbing mixing fixture with a hot and cold water intake, a mixing chamber, and a mixing water outlet, in which the quantity of the flow and the mixing temperature are regulated by means of valve discs that can be adjusted by motor, a multi-disc mixing valve that adjusts both the quantity and the mixing temperature one after another is installed.
