<p>PURPOSE: To further make the appearance of an adjusting member and an electrically operated valve attractive by arranging at least the adjusting member and the electrically operated valve into a narrower space in a sanitary mixer tap system. CONSTITUTION: The electrically operated sanitary mixer tap system comprises a hallow 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. Each flow path 22, 23 for cold and hot water open in the chamber 21. A groove 27 on the outside of the hollow piston 17 cooperates with each flow path 22, 23 and thus determines the mixing ratio of the cold and hot water of the mixed water flowing out of the fitting. At least a part extends through the interior of the hollow piston 17 in the flow paths of mixed water. A diaphragm 30 and an abutting member 34 as the closing members of an electrically operated valve 29 are arranged into the internal region of the hollow piston 17, and these control the discharge of mixed water. This arrangement of the closing members 30, 34 radially inside the hollow piston 17 facilitates a particularly space-saving construction.</p> |
