Abstract

L'invention concerne un aérateur (101) ayant un boîtier (1) d'aérateur qui (1) peut être inséré dans une sortie d'eau d'un raccord de sortie sanitaire et qui délimite un espace intérieur de boîtier dans lequel un séparateur (2) de jet présentant des ouvertures (3) de séparation qui (3) divise l'eau s'écoulant à travers une pluralité de jets individuels, et ayant un redresseur d'écoulement (5) formant la face d'extrémité de sortie (A) de l'aérateur (101, 106, 110, 115, 118, 121), qui (5) présente une pluralité d'ouvertures (6) de sortie, un dispositif de commande (4) de jet étant disposé à l'intérieur du boîtier dans le chemin d'écoulement entre le séparateur (2) de jet et le redresseur d'écoulement (5), lequel (4) comportant des pièces de commande (7) orientées transversalement à la direction d'écoulement de l'eau s'écoulant à travers. L'aérateur (101) selon l'invention est caractérisé en ce que le redresseur de flux (5) et le dispositif de commande (4) de jet peuvent être insérés dans le boîtier d'aérateur (1) à partir du côté de sortie (A) de l'aérateur (101, 106, 110, 115, 118, 121), le dispositif de commande (4) de jet présente au moins une paroi intérieure (8) sur laquelle les pièces de commande (7) sont formées sur le côté plat, et en ce que le redresseur d'écoulement (5) et/ou le dispositif de commande (4) de jet peuvent être fixés au moyen d'une liaison par complémentarité de forme ou par friction dans le boîtier d'aérateur (1).
