Description

The invention relates to a switching valve comprising a housing having at least one inlet channel and at least two outlet channels, wherein a diverter is arranged for selectively connecting at least one inlet channel with at least one outlet channel.

Valves for assigning an inlet-side water flow to several drain channels are known in different versions. For example, such Umstellventile be used for bathtub fittings, which often have an additional outlet that forms the water inlet via a flexible supply line of a shower connected shower. Shower systems can also have several shower heads of different types or, in addition to head and hand shower also side showers. For the respective selection of the individual water supply point such changeover valves are used. A reversing valve of the generic type is for example in the DE 10 2007 026 828 A1 described. In this case, a disk control, consisting of a fixed a movable ceramic sealing disc is used, which is arranged in a cylindrical valve housing. Another Umstellventiloberteil for introduction into a bathtub tap is in the DE 10 2011 009 774 B4 described. Again, a disc control, consisting of a non-rotatable inlet disc and a relative to this rotatable control disc is used, which is arranged in a head piece.
