  • 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: 7726344
    Abstract: The disclosure relates to a device for dynamic adjustment of a water flow, used to stabilize the operational mode of a thermostatic mixing tap. The inventive device includes a valve consisting of a piston and a return spring forcing the piston into a first position, said piston being displaced into two positions according to the flow. When the flow is lower than a threshold value, the piston is located in the first position and a flow limited means limits the flow. When the flow exceeds the threshold value, the piston is displaced into the second position and the flow limiting means is obviated.

  • Patent number: 7681803
    Abstract: Disclosed is a device for taking showers at alternating temperatures. The device is used with a delivery pipe for one or several shower heads, a hot water pipe that is connected to the outlet of a thermostatic mixer, and a cold water pipe which is connected to a water pipe. The device includes a switching means regarding the hot water pipe and the cold water pipe. The switching means is provided with a first control means and a second control means, both of which can be moved into two positions in such a way that the second control means is in a first position when the first control means does not connect the delivery pipe to the cold water pipe while the second control means is in a second position when the first control means connects the delivery pipe to the cold water pipe.

  • Patent number: 6823892
    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: 20040069358
    Abstract: A plate (9, 10) made of hard material, having at least one flat surface machined by means of lapping and intended to be used as a member to control the flow in a hydraulic equipment unit, that consists of a thermosetting synthetic polymer, is made by means of molding and has in the regions different from its flat surface configurations suitable for cooperating directly with some specific members of a hydraulic equipment unit. The thermosetting synthetic polymer can be mixed with a solid lubricant. When the plate is a fixed plate, it presents the characteristic configurations of a bottom member that is directly connected to the cage (1) of a cartridge, whereas when the plate is a movable plate, it presents the characteristic configurations of a slide that cooperates directly with guide members and with members for operating the cartridge.

  • 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: 6557785
    Abstract: The showerhead (10) includes a main housing (12) that forms the central supply inlet (16), a supply passage section (20) for the central inlet and a peripheral deflector (22). A disc (26) is applied to the main housing (12). The Venturi passages (40) are made up between housing (14) and the disc (26). A showerhead (10) is intended to deliver an aerated stream of water that has passed through and has been aerated by Venturi passages 40. The Venturi passages (40) radially extend from the supply inlet (16) toward the periphery (22) of the head (14). An air intake passage (44) communicates with the ambient exterior and also communicates with the Venturi passage between its nozzle (50) and diffuser (52). The deflector (22) is arranged to divert the aerated stream of water coming out of the individual Venturi passages in order to deliver them in substantially axial direction perpendicular to the plane (29) of the showerhead.
