  • 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: 7681597
    Abstract: The disclosure relates to a thermostatic mixer, including a device for the dynamic regulation of 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: 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: 7681598
    Abstract: The disclosure relates to a device for dynamic control of a water flow, including the following items in a body: a feed chamber, a discharge chamber and a piston arranged between the feed chamber and the discharge chamber. The piston can be displaced from a first position, which is offset towards the feed chamber and wherein the piston narrows the flow between the feed chamber and the discharge chamber, and a second position, which is offset towards the discharge chamber and wherein the piston does not narrow the flow between the feed chamber and the discharge chamber.
