APPARATUS FOR MIXING COLD AND HOT WATER, AND FOR DISTRIBUTING THE WATER MIXTURE Abstract of the Disclosure A cold and hot water mixing faucet comprises an inlet valve each for the cold and hot water to deliver cold and hot water to a mixing chamber. Each valve includes a valve housing and a membrane thereon and defining a counterpressure chamber therewith. The membrane is movable between an open position and a closed position for selective supply of water to the mixing chamber, and a conduit interconnects each counterpressure chamber and the mixing chamber. A thermo- statically-controlled water distribution control device is associated with the conduits and is arranged for actuation of each inlet valve in inverse directions to maintain a predetermined water temperature in the mixing chamber. A water flow blocking device is associated with each valve conduits upstream of the thermostatically-controlled device and is actuatable independently of the control device for blocking the flow of water through the conduits of both valves to prevent escape of water from the counterpressure chamber whereby the pressure in the counterpressure chambers increases until it presses the membranes into the closed position without actuation by the water distribution control device.
