Thermostatic shower valve

摘要

Embodiments include thermostatic valves for showers and tubs in which the temperature is regulated by a thermostatic motor/element. Both the flow from the valve and the temperature are controlled by a rotary stem. Hot and cold water is pre-mixed by passage through the coils of a return spring into a mixing chamber and a ceramic valve at the top of the mixing chamber controls flow of mixed water from the mixing chamber into an outlet chamber where fluctuations in the water temperature are eliminated before the water is conveyed to the shower or tub.
