<p>A mixing valve for controlling both total volume of flow and relative volumes of flow through two inlet valves, such as hot and cold water valves, has the two valves bearing against a pressure plate which is tiltable on an axis offset with respect to the two valves. By increasing or decreasing the angle of tilt of the pressure plate, both valves are caused to open or close, increasing or decreasing the total volume of flow. By rotating the axis of tilt of the pressure plate relative to the valves, one valve or the other is caused to open or close more than the other, varying the relative volumes of flow through the two valves. Thermostat means may be provided to control rotation of the pressure plate to maintain a uniform temperature of the mixed outflow of the two valves.</p> |
