Abstract

L'invention concerne un réservoir de chasse d'eau pour cuvette de W-C. Ce réservoir comprend un grand robinet de chasse d'eau et un petit robinet de chasse d'eau pour faire varier la quantité d'eau de chasse fournie à une cuvette de W-C entre une quantité importante et une faible quantité. Le grand robinet de chasse (A) et le petit robinet de chasse (B) sont disposés de manière coaxiale. La flottabilité conférée aux disques (5, 7) des robinets permet de détecter les niveaux d'eau correspondant à la fermeture des robinets, ce qui assure le contrôle de la fermeture des robinets de chasse (A, B).
