Abstract

Un diffuseur économiseur d'eau (1), avec lequel un utilisateur perçoit une vitesse d'écoulement relativement plus élevée que la vitesse d'écoulement réelle, comprend une chambre de chasse (10) logeant un disque de distribution (40), et un élément accélérateur (20) fixé sur la chambre de chasse (10), ledit élément accélérateur (20) comportant plusieurs orifices pour permettre un écoulement à flux multiple généré par le diffuseur économiseur d'eau (1). Un orifice central (42) du disque de distribution (40) peut être dimensionné par l'usager pour produire une vitesse d'écoulement spécifique par rapport à une pression d'alimentation en eau donnée. Le diffuseur économiseur d'eau (1) peut être utilisé dans un système de distribution d'eau pour produire une vitesse d'écoulement uniforme prédéterminée pour tous les secteurs d'une maison de plain-pied ou d'un bâtiment à étages.
