<p>Valve include an assembly (10) comprising a mixing valve element (62) in a first mixing chamber (78) directly coupled to a stepper motor (70) for axial movement of the element within the first mixing chamber (78), in a manner to adjust the ratio of hot water and cold water flowing into the first mixing chamber (78), an electronic control logic module (72) for interfacing between a flow sensor (88) and a temperature sensor (90) located in a second mixing chamber (80), the second mixing chamber (80) communicates with the first mixing chamber (78) and receives partially mixed fluids from the first mixing chamber; the second mixing chamber contains a flow sensor (88) comprising a rotary turbine (84) with blades, each blade effecting a signalling pulse as the turbine simultaneously mixes the hot and cold fluid streams to effect complete temperature uniformity of the mixed fluid stream in the second mixing chamber (80).</p> |
