  • Patent number: 7832650
    Abstract: A hot water-water mixing faucet holds a control valve body in a balanced position between a bias spring and a temperature-sensitive coil spring. An adjusting screw 6a supports the bias spring in an axial direction to change setting of the supporting position of the bias spring, and a rear end side of the bias spring is supported by a supporting member which is formed separately from the adjusting screw. The supporting member is slidably inserted in the axial direction into a through-hole provided on the adjusting screw and is connected detachably to the adjusting screw by an abutting section provided in an area protruding from the through-hole toward the bias spring side. A lifting spring biases the supporting member to pull the supporting member back toward the side opposite to the bias spring to the adjusting screw 6a.

  • Patent number: 7740183
    Abstract: The disclosure relates to a thermostatic mixer, including a device for the dynamic regulation of the cold water flow which supplies the mixer. A resistance is generated to the flow of cold water supplied to the thermostatic mixer when small flows of mixed water are required, and said resistance is lifted or reduced when large flows of mixed water are required. Said operation is automatically carried out by devices for dynamic regulation of flow, whereby the flow cross-section provided for the incoming cold water is reduced when the drawn flow is reduced and a larger flow cross-section reestablished when a larger flow is required.

  • Patent number: 7740182
    Abstract: A valve assembly for a water circulation system includes a bypass valve with an inlet and an outlet that permits recirculating flow of water from a hot water line of the water circulation system. The valve assembly also includes a shut-off valve with a valve body having a hot water inlet and a hot water outlet configured to be coupled to a fixture of the water circulation system. The shut-off valve is located proximate the fixture and operating in an open position allowing water to flow to the hot water outlet and a closed position restricting water from flowing to the hot water outlet. The shut-off valve is configured to move automatically from the open position to the closed position in a controlled manner to limit discharge, from the hot water outlet, of water having a temperature below a desired level.

  • Patent number: 7163157
    Abstract: An automatic compensating valve, e.g., for individual shower and tub/shower combination fixtures, has a valve body defining cold and hot water inlet flow passageways, a mixing chamber, a mixed temperate water outlet flow passageway, and an axial bore. The valve includes a plunger that defines, with other elements of the valve, a first orifice for communication of the cold water inlet with said mixing chamber and a second orifice for communication of hot water inlet with mixing chamber. The plunger is mounted within a mixing subassembly for axial movement within the bore, including in response to temperature of water within the mixing chamber to vary the ratio of flow of cold water through the first orifice to flow of hot water through the second orifice. The first orifice and the second orifice are arranged for flow of water transverse to axial movement of the plunger within the bore.
