Abstract
A new use of a flow rate regulating device ( ) 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 ( ) during the transitory period of regulation when the pressure of the water supplied to one of the inlets ( ) of the thermostatic mixing device ( ) varies abruptly with respect to the pressure of the water supplied to the other inlet of the thermostatic mixing device ( ). The new use consists of the insertion of the flow rate regulating device ( ) in the passage of at least one of the flows of supply of cold water and hot water (inlets ) directed to the thermostatic mixing device ( ). The flow rate regulator ( ) can be inserted on the passage of both supply flows of cold and hot water, of the hot water supply flow only, or, and preferably, of the cold water supply flow only.
