Abstract
A sanitary mixing unit, especially in the form of a single thermostat, has a cold and hot water inlet and a mixed water outlet. Valves for shutting off and controlling the water flow are arranged before the thermostat control and thus before the mixing chamber in the direction of flow. The valves are simultaneously activatable by a spindle. The movable valve closing members are fine adjustable independent from one another relative to the respective valve seats for a secure shut-off. An automatic fine adjustment of the movable valve closing members during shut-off of the mixing unit is provided by employing a central spindle with a fixedly arranged toothed wheel at its end section facing the valves. The toothed wheel engages two spur gears which are cooperating via a slip coupling with two single spindles of the valves.
