ABSTRACT:
A fixture for thermostatically mixing hot and cold water from hot- and cold-water pipes. The diameters of the annular axes of seals provided on both ends of a control valve are equal to the inside diameter of the valve guide for the control valve. The space left between the external surface of a temperature sensing element and the internal surface of the casing for the temperature sensing element is so narrow as to be adapted to allow the temperature sensing element to quickly respond to a change in the water temperature. A spring engages at opposite ends against a main valve and the control valve so as to bias the control valve against a valve seat.
