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.
