Abstract
A thermostatic mixing valve contains a control bush, which can be displaced by an expansion element, which is exposed to the mixing water temperature. As a function of the mixing water temperature and the set desired temperature, the control bush is displaced for simultaneously opening the hot water supply and closing the cold water supply or vice versa. According to the invention there are two control openings for the cold water and two control openings for the hot water.
