This invention relates to a thermostatic mixing valve that includes a housing, temperature control valves in the housing that have axially spaced cold and warm water regulating bases and a valve element for cooperating with the above valve bases to reversely vary the flow of the cold water and warm water to the housing outlet port, and cold and warm water quantity setting valves upstream of the temperature regulating valves for controlling the quantity of the cold and warm water flow from the housing cold water and warm water supply ports to the cold and water regulating valves respectively. The quantity setting valves have axially spaced quantity setting valve bases and a common valve member axially movable relative to the quantity setting valve bases for controlling downstream flow from the supply ports, the pressure at the supply ports acting in the same axial direction against the common valve member. Adjustable quantity control mechanism is provided for controlling the axial position of the quantity cold water base relative to the common valve member and the quantity warm water base, and adjustable temperature control mechanism including a thermostatic operating element for actuating the valve element to control the temperature of water at the outlet port. |
