Abstract: A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from the piston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.

Abstract: A temperature control valve that effectively manages fluid pressure therethrough, including pressure differentials which may exist therein, such as from the upstream port to the downstream port, and about a piston slidingly disposed therewithin proximate a fluid flow path. In one embodiment a 3 stage valve is provided whereby fluid flows therethrough when the piston is in a first position, fluid flow is inhibited in a second piston position, and an override third position whereby fluid flows therethrough. When the piston is in the second position, the fluid pressure differential across the piston is balanced and an axial spring force on the piston is relatively small, thereby reducing any subsequent axial force required to advance the piston to the third free flow position, and allowing the valve to be comprised of cheaper materials including plastic.

Abstract: A temperature-controlled valve allows the flow of water to be terminated automatically when the water flowing through the device reaches a specific temperature. The flow may thereafter be released automatically or manually, depending upon the application. The technology may be used in a variety of contexts, including, for example, stand-alone consumer or commercial valves, embedded applications, and custom-designed valves.
