Abstract: A faucet has a fixture body in fluid communication with a pressurized supply of hot water. The fixture body has a spout outlet configured to dispense water from the fixture body. At least one operating valve is coupled to the fixture body for controlling a flow of water to the spout outlet. A bypass valve is disposed in the fixture body for controlling a recirculating flow of water through the fixture body, where the bypass valve changes state when heated and when cooled to block and permit the recirculating flow of water based on a temperature of the water.
Abstract: A water control fixture includes a housing having a plurality of ports defining a hot water inlet port, a bypass port, and a fixture outlet port, wherein water is dispensed via the fixture outlet port. At least one operating valve is disposed in the housing for controlling a flow of water from the hot water inlet port to the fixture outlet port. A bypass valve is disposed in the housing for controlling a flow of water from the hot water inlet port to the bypass port.
Abstract: A water control valve configured for use with a bypass valve to automatically bypass cold or tepid water in a hot water supply line so as to maintain hot water at the fixture. The water control valve is useful for shower/tub facilities and for appliances such as washing machines and dishwashing machines. The water control valve for use with shower/tub facilities is adapted for the bypass valve to attach to or be adjacent to the water control valve by utilizing bypass ports, passageways and/or connectors. The water control valve for use with appliances is adapted to have a second outlet for connecting to a second water control valve or, for combination service valves, to have the bypass valve disposed in the tubular section between the hot and cold water components. The preferred bypass valve is a thermostatically controlled bypass valve of the type having a thermal actuating element.
