20150028112 | Thermostatic mixing valve - Embodiment thermostatic valves are protected against damage to the wax motor from the leakage of hot water into the valve when the hot water inlet is closed. Embodiments include an improved temperature motive means with fewer parts than conventional valves and with an improved sealing relation between the wax motor/shuttle and the water ports. | 01-29-2015 |
20150027551 | Thermostatic valve with anti-failure provisions - Embodiments include eyewash valves in which the temperature of the water emerging from the valve is thermostatically controlled by a wax motor which regulates the flow of hot and cold water through the valve. Embodiments include provisions for continuing water flow through the valve despite failure of the hot water supply. Embodiments also include provisions for water flow through the valve despite failure of the wax motor in the upper position or in the lower position. | 01-29-2015 |
