Title
(EN) TOILET WATER SAVER
(FR) ÉCONOMISEUR POUR CHASSE D'EAU
Abstract
(EN) The toilet water saver includes a toilet tank and flushing valve assembly that efficiently uses the water in the tank for the particular waste being flushed. The flushing valve assembly has two flapper valves, one flapper valve disposed vertically higher than the other, and an actuator that operates one valve singly or both flapper valves simultaneously at the user s option. The disposition of the valves with respect to the maximum tank capacity level defines respective first and second volumes of water to be used. The higher disposed flapper valve is operated to drain a smaller volume of water for the common liquid wastes while the lower disposed flapper valve is operated to drain a much greater volume for solid waste.
(FR) La présente invention concerne un économiseur pour chasse d'eau comprenant un réservoir de chasse d'eau et un ensemble robinet de chasse qui utilise efficacement l'eau contenue dans le réservoir en fonction des matières à évacuer. L'ensemble robinet de chasse comporte deux clapets dont l'un est disposé verticalement plus haut que l'autre, et un actionneur qui met en œuvre un seul clapet à la fois ou les deux clapets simultanément en fonction du choix de l'utilisateur. La disposition des clapets par rapport au niveau maximum de capacité du réservoir définit deux volumes d'eau différents à utiliser. Le clapet disposé le plus haut est mis en œuvre pour vider un plus petit volume d'eau pour des matières liquides habituelles, alors que le clapet disposé le plus bas est mis en œuvre pour vider un bien plus grand volume dans le cas des matières solides.
