  • a closing of the inflow opening of the flow chamber or of the flow channel is provided by abutment of a part of the elastic valve body on a sealing surface.
  • a jet regulator usually has a housing with an external thread, which can be screwed into the outlet of a sanitary fitting.

Abstract

L'invention concerne un brise-jet pour l'orifice de sortie d'une pièce de robinetterie sanitaire ou pour une douche, lequel comprend au moins deux chambres d'écoulement ou canaux d'écoulement (12, 13) qui présentent respectivement une ouverture d'entrée et respectivement une ou plusieurs ouvertures de sortie d'eau (121, 131). Selon l'invention, la commande de l'arrivée d'eau pour chaque chambre d'écoulement ou canal d'écoulement (12, 13) est effectuée par une soupape dotée d'un corps de soupape élastique (15), qui est disposée en amont des chambres d'écoulement ou canaux d'écoulement (12, 13) et qui ferme ou libère sélectivement leurs ouvertures d'entrée avec le corps de soupape élastique (15). Une modification de la pression d'eau existante ou un actionnement mécanique au moyen d'un actionneur (17) entraîne une déformation du corps de soupape élastique (15) et par conséquent un changement de la position de la soupape.
