  • Patent number: 7886987
    Abstract: A thermostatic valve incorporated within a plumbing system for regulating the flow of fluid. The thermostatic valve includes two valve assemblies operatively cooperating to preclude the flow of scalding water. The first valve assembly and second valve assembly respond to different fluid temperatures, as well as, over separate periods of time. The thermostatic valve can be incorporated in an “end-line” device such as a showerhead or faucet assemblies to create an “anti-scaled” plumbing fixture. The invention includes a valve housing having a first compartment and a second compartment, a fluid passageway, a first valve assembly, a second valve assembly, a first spring, a first stopper, a first flange, a first thermostatic cylinder, a second spring, a second stopper, a second flange, a second thermostatic cylinder, and a third spring.
