Abstract

Siège de W-C à chasse d'eau comportant une cuvette (2) recevant les eaux de chasse, une couronne de distribution d'eau (1) placé à la périphérie supérieure de la cuvette, un siphon (3) sensiblement en U inversé communiquant avec la base de la cuvette et comportant une partie médiane (37) formant barrage, et une amenée d'eau (5, 6) à la couronne (1) et à la cuvette (2) placée à l'arrière de cette dernière. Le siphon comporte un séparateur (4) d'eaux de chasse dont la surface latérale intérieure présente un décrochement brusque entre la partie formant barrage (37) et le conduit de chute (33). En outre, un moyen de freinage du flux (63) est placé entre l'amenée d'eau (5, 6) et la couronne de distribution (1) pour retarder l'arrivée de l'eau dans cette dernière.
