Abstract

L'invention concerne un brise-jet (1) comportant un boîtier de brise-jet (4) présentant une partie (5) qui est dotée d'une paroi de boîtier (7) en forme de douille et dont l'espace intérieur de douille est relié pour former une seule pièce avec un dispositif brise-jet (8) orienté transversalement au sens d'écoulement, ce dispositif comportant une pluralité d'ouvertures d'écoulement (9) pour subdiviser le courant d'eau en une pluralité de jets individuels, un tamis adaptable (11) étant maintenu de manière amovible dans la partie (10) de l'espace intérieur de douille côté arrivée subdivisée par le dispositif brise-jet (8). L'invention est caractérisée en ce qu'un filet externe (12) est prévu côté périphérique externe sur la partie (7) de la paroi de boîtier (7) délimitant la partie (10) de l'espace intérieur de douille côté arrivée. Ce filet externe (12) est façonné dans un segment du boîtier de brise-jet (4) qui n'est pas particulièrement sollicité par la pression de l'eau et qui, par conséquent, peut avoir une paroi comparativement mince, aucune autre pièce d'insertion qui pourrait rétrécir davantage la section intérieure d'écoulement ne devant être logée, en règle générale, dans le boîtier de brise-jet (4).
