Water fitting for feeding separate cold and hot water flows directly to a thermostat-controlled mixing valve comprises a mixing valve and a flow-regulating and reversing rotary valve

摘要

Water fitting comprises a housing having at least one inlet opening for cold and hot water and two outlet openings for cold, hot or mixed water. A mixing valve and a flow-regulating and reversing rotary valve are arranged in the housing. The flow-regulating and reversing rotary valve has additional synchronously closable openings (401-404) for cold and hot water flowing separately to the mixing valve. Preferred Features: The flow-regulating and reversing rotary valve contains a valve seat disk (40) made of a hard material and having a finely ground sealing surface (400) and a rotating control disk made of a hard material and having a finely ground sealing surface positioned on the sealing surface of the valve seat disk. When the control disk is in the shut-off position, the opening for the separate cold and hot water flows and the openings (405, 406) for the outlets to a first and a second consumer are closed.
