Title (EN) TOILET FLUSH VALVE
(FR) ROBINET DE CHASSE D'EAU POUR W.C.
Abstract:
(EN) The invention provides a direct flushing device (10) for cisternless-type flush toilets, the flushing device (10) includes an actuating means (12) for opening a passageway (14) for the passage of water to a toilet bowl having an outlet at its bottom sized to accommodate liquid and solid waste, characterized in that said passageway (14) is provided with a flow cross-sectional area restricting means for providing at least one restricted opening (16) downstream of said actuating means (12), and said passageway (14) is also provided with air inlet means (18), whereby the flow velocity of the water flowing through said restricted opening (16) is increased and air is sucked into said water flow to increase turbulence of the water and to enhance its ability to disintegrate and discharge solid waste from said toilet bowl.
(FR) L'invention concerne un dispositif de rinçage direct (10) pour toilettes à chasse d'eau du type sans réservoir. Le dispositif de rinçage (10) inclut un moyen d'actionnement (12) qui ouvre un conduit (14) de chasse d'eau vers une cuvette de W.C. dont la partie inférieure présente une sortie dimensionnée pour recevoir des déchets liquides ou solides. Le dispositif se caractérise en ce que ledit conduit (14) comporte un moyen de restriction d'écoulement présentant une à zone de section transversale, qui fournit au moins une ouverture étranglée (16) en aval du moyen d'actionnement (12). Le dispositif se caractérise aussi en ce que le conduit (14) comporte également un dispositif d'entrée d'air (18) grâce auquel la vitesse d'écoulement de l'eau à travers ladite ouverture étranglée (16) augmente et l'air est aspiré dans le flux d'eau pour en augmenter la turbulence et améliorer sa capacité à désintégrer et évacuer les déchets solides de la cuvette de W.C.
