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.
