    Abstract: A method and a device are provided whereby a container can be continuously filled with mixed water from separate cold and hot water pipes K, W within a short time and the temperature T of the mixed water is kept as constant as possible at a predetermined value Ts during the supply process. According to the method according to the invention, the regulating process always takes place only in one direction from higher to lower temperature values. The method is implemented by a regulator 1 to 6 with separate intake pipes K and W for cold and hot water and a mechanical control element 6 which is only moved in one direction. The essential advantage of the method according to the invention is that it can be implemented very cheaply, especially a synchronous motor without reversal of the direction of rotation can be used as a drive for the control member 6. Possible perturbations in the hot water system can by intercepted to a sufficient extent by compensation which is easy to implement.

    Abstract: A valve installed at the inlet of a thermostatic mixing device for automatically stabilizing the operation of the thermostatic device by maintaining the pressure within the thermostatic mixing device close to the water supply pressure, thereby making the thermostatic device response to small pressure changes while maintaining the fluid flow through the device. The valve comprises a tubular body inserted within the water supply line, a holding seat within the tubular body, a cursor that moves within the valve body with respect to the seat, the cursor moving between a first position where the seat is partially occluded and a second position where the seat is substantially clear. The cursor is subjected to the pressure existing inside the thermostatic mixing device, and a spring positioned with the valve body that acts upon the cursor to urge the cursor towards the first cursor position.

  • Publication number: 20040173688
    Abstract: A freestanding or Roman bathtub plumbing system including a bathtub filler (such as a spout and/or hand-held shower) controlled by a compact thermostatic mixing valve. The thermostatic mixing valve is installed in a bathtub plumbing set having a hand-held shower accessory. The thermostatic mixing valve receives hot and cold water from the main hot and cold water inlet pipes, respectively, located upstream of the respective hot and cold water control valves used to control the supply of water to the fillers. The hot and cold water feed pipes are each hydraulically connected to a first respective hot and cold water inlet of the thermostatic mixing valve. The bathtub fillers are hydraulically connected to the outlet of the thermostatic mixing valve, such as by a pipe or flexible hose.

  • Publication number: 20040149831
    Abstract: The present invention provides a device for monitoring the operation of a control valve (1), which is adapted to supply fluid at a predetermined temperature via an outlet (4). The device includes a sensor (10) adapted to be coupled to the outlet (4) so as to sense the temperature of the fluid. An indication device (16) and a processor (18) are provided. In use, the processor is adapted to determine the temperature of the fluid from the sensor and, provide an indication of this via the indication device.

  • Patent number: 6769480
    Abstract: An apparatus (100) controls the temperature of air flow from a temperature control system (10) The apparatus (100) includes a blend door (150), an output gear (140), and a biasing mechanism (124) The biasing mechanism (124) facilitates rotation of the output gear (140) in a first rotation direction (136) and impedes rotation of the output gear (140) in a second rotation direction (138) opposite the first rotation direction (136) This results in the torque necessary to rotate the output gear (140) in the first rotation direction (136) being substantially equal to the torque necessary to rotate the output gear (140) in the second rotation direction (138).

  • Patent number: 6708895
    Abstract: A new use of a flow rate regulating device (5, 6) is disclosed whose feature consists of the fact that, when inserted in a water pipeline, it permits the passage of a flow of water having a substantially constant flow rate and predetermined in keeping with the variation within certain limits of the pressure at which the water is supplied to the device, thus constituting a variable resistance that is opposed to the water flow. The new use is especially designed to perform the function of reducing the temperature peak presented by the mixed water drawn from a thermostatic mixing device (1) during the transitory period of regulation when the pressure of the water supplied to one of the inlets (2, 3) of the thermostatic mixing device (1) varies abruptly with respect to the pressure of the water supplied to the other inlet of the thermostatic mixing device (1).

  • Patent number: 6705534
    Abstract: A shower control system for facilitating a user's control of the temperature and pressure of water used during a shower. The shower control system includes a shower assembly having a pair of inlet pipes. A first of the inlet pipes is designed for being in fluid communication with a building cold water supply. A second of the inlet pipes is designed for being in fluid communication with a building hot water supply. A stem pipe of the shower assembly is in fluid communication with the inlet pipes. A shower head of the shower assembly is in fluid communication with the stem pipe. A mixing assembly is operationally coupled to the shower assembly. The mixing assembly is designed for controlling pressure and temperature of water sprayed from the shower head. A power assembly is operationally coupled to the mixing assembly for providing power to the mixing assembly.

    Abstract: A thermostatic valve for sanitary fittings contains an extensible material element, which is exposed to the temperature of the mixed water resulting from the mixing of hot and cold water. The extensible material element is operatively connected to two closing bodies each associated with a valve and which move simultaneously when the mixed water temperature changes.

    Abstract: A thermostatic mixing valve for hot and cold water has two-stage inlet chambers for the hot and cold water flows respectively. The inlet chambers distribute the flows uniformly with respect to porting for admitting the flows to the mixing chamber to reduce asymmetric flow patterns and promote thorough mixing of the flows within the mixing chamber.
