ABSTRACT:
An electrically operated sanitary mixer tap system comprises a hollow piston (17) for adjusting the temperature, which in particular may be a rotary piston. The hollow piston (17) moves in a chamber (21) of the housing (1) of the mixer tap system, into which the flow paths (22, 23) for cold and hot water open. A particular structure (27) on the outside of the hollow piston (17) cooperates with the openings of the flow paths (23, 27) and thus determines the mixing ratio of the mixed water flowing out of the fitting. Its further path to the outlet of the sanitary fitting leads at least in regions through the interior of the hollow piston (17). Located at this point are (at least) the closing members (30, 34) of an electrically operated valve, which in this way controls the flow of mixed water to the outlet of the fitting. This arrangement of the closing members (30, 34) radially inside the hollow piston (17) facilitates a particularly space-saving construction (FIG. 4).
