ABSTRACT:
An automatic fluid mixing valve comprises temperature sensing means provided in a body of the valve for automatically mixing high and low temperature fluids to provide a mixed fluid having a predetermined temperature, and pressure control means for controlling the pressure ratio of said low temperature fluid to the high temperature fluid at a predetermined value. The pressure control means serves to maintain a ratio of fluid flow of the low and high temperature fluids at a predetermined value thereby maintaining the temperature of the mixed fluid.
