<p>A fluid control system includes a valve and a restrictor. The valve is configured to regulate the proportion at which a first fluid and a second fluid are mixed together. Based on the pressure drop across the restrictor, the valve further regulates the overall flow rate of the mixed first and second fluids. In one form, the valve includes a pair of spools that regulate the proportion and flow ra te of the fluids. In another form, the valve includes a thermostatic element that regulate the proportion at which the first and second fluids are mixed together so as to control the temperature of the mixed fluids. The valve in a further form incorporate s a pair of diaphragm valves.</p> |
