Abstract: Mixing valve turbulence generators and methods are disclosed. Embodiments include turbulence generation apparatuses and methods that increase the turbulence of, impart swirl to, reverse the direction of, create tortuous paths for, and/or accelerate the mixing of hot and cold fluid within a valve assembly. Alternate embodiments include angled radial slots, angled surfaces and fin-like baffles to enhance the mixing of hot and cold fluids.

Abstract: A mixing valve (10) includes a valve body (12) having a hot fluid inlet (14), a cold fluid inlet (16), a mixed fluid outlet (18), and a cavity (20) in the valve body (12) between the inlets (14, 16) and the outlet (18). Mixing valve (10) includes a liner (30, 130, 230, 430, 530, 630, 730, 830) positioned in valve body (12) and a valve member (40, 140, 240, 340, 440, 540, 640, 740, 840) movable therein between a first position restricting the flow of hot fluid and a second position. Liner (30, 130, 230, 430, 530, 630, 730, 830) includes a downstream valve seat (74, 174, 274, 474, 574, 674, 774) that, when engaged by valve member (40, 140, 240, 340, 440, 540, 640, 740, 840), restricts flow of hot fluid past valve member (40, 140, 240, 340, 440, 540, 640, 740, 840).

Abstract: The present invention is directed to methods and apparatus for tempering the temperature of a liquid in a fluid conducting system. More particularly, some embodiments of the invention relates to tempering the temperature of water supplied to a fixture from a water heater in a fluid conducting system. The system can include a heater for heating the fluid and a diffuser for slowing the rate at which water provided to a decontamination fixture is heated.

Abstract: The present invention is directed to methods and apparatus for tempering the temperature of a liquid in a fluid conducting system. More particularly, the invention relates to tempering the temperature of water supplied to a fixture from a water heater in a fluid conducting system. In some embodiments, the invention includes a restrictor for decreasing the fluid pressure in one of the hot inlet or cold inlet of the mixing valve.

Abstract: A thermostatic mixing valve for the mixing of a first fluid and second fluid is disclosed. The thermostatic mixing valve includes a valve body having a first fluid inlet, a second fluid inlet, and a mixed fluid outlet. The thermostatic mixing valve also includes a valve member configured to control the rate of flow of at least the first fluid. The valve member includes a thermostatic control device in communication with the mixed fluid and a shuttle coupled to the thermostatic control device, configured for movement within a liner, and oriented to adjustably engage the flow of at least the first fluid through at least one opening within a wall of the liner, the direction of flow of the first fluid being at least partially transverse with respect to the shuttle. At least one fluid inlet may include a check valve configured to prevent fluid from flowing out of the valve through the inlet.
