Abstract
A mixer valve for sanitary fixtures is provided. The mixer valve includes a pressure regulator, a piston, a thermostatic element, and a flow diverter. The pressure regulator is operable to regulate hot water flow from a hot water inflow opening and cold water flow from a cold water inflow opening to a mixing chamber. The piston is operable to regulate a temperature of mixed water flow resulting from mixing of the hot water flow and the cold water flow in the mixing chamber. The thermostatic element is operable to move the piston in response to changes in the temperature of the mixed water flow. The flow diverter is operable to divert the mixed water flow from the mixed water outflow opening to multiple connected users. The pressure regulator is fluidically upstream of the piston and the thermostatic element. The piston and the thermostatic element are fluidically upstream of the flow diverter. The flow diverter is located inward of the pressure regulator in the mixer valve or between: (1) the pressure regulator and (2) the piston and the thermostatic element.
