ABSTRACT:
A thermostatic control valve assembly for use in continuously mixing a hot first fluid with a cold second fluid to continuously produce a mixed fluid at a constant temperature. The valve assembly includes an improved mixing dome defining a mixing chamber that facilitates thorough mixing of the hot and cold fluids over a wide range of flow rates, including rates as low as two gallons per minute. The improved mixing performance is accomplished by a plurality of baffles sequentially disposed along the flow path within the mixing chamber. Each baffle defines an elongated opening which is angularly displaced from the elongated opening of the other baffles to turn the fluid flow, thereby optimally mixing the hot and cold fluids over a wide range of flow rates.
