摘要

The multi-way mixing valve has an outlet and at least four inlets, to each of which is allocated an operating point (n) inside the overall operating range extending between two end points. Only one inlet is fully open to the outlet by a movably mounted operating component, and all the other inlets are closed by this operating component. Each of the two end points corresponds to one of these operating points so that the whole operating range is divided into n-1 sub-sections of which each is bounded by two operating points. During the passage of a sub-section the initially completely opened inlet belonging to the first operating point of this sub-section is continuously closed and the inlet belonging to the other operating point is continuously opened, whereby all other inlets are closed.
