Abstract: A device for controlling the filling of a cistern in a main reservoir of a toilet flushing system includes a water inlet controlled by a valve. The closing of the valve is controlled by a float that is movable from a high position to a low position. The float is contained in a float housing in the high position. The float housing connects to the main reservoir by at least one siphon having two tubes: a suction tube linked to the float housing; and a discharge tube being linked to the main reservoir and opening into an auxiliary reservoir. There is a control mechanism provided with a mechanism for priming the siphon, wherein shifts between an initial position and an actuated position of the control mechanism result in overpressure or underpressure at the siphon so as to control draining of the float housing.

Abstract: An apparatus for detecting leaks and for shutting off the water flow has a flushing cistern having a water inlet that is controlled by main valve, a filling column connected to the flushing cistern, a fluid compartment having a float therein and an actuating mechanism. The main valve has an operating lever that is operable to close the main valve. The float is cooperative at the operating lever so as to pivot the operating lever when the flushing cistern is full of water. When the float lowers in the float compartment as the float compartment is emptied, the actuating mechanism causes the operating lever to open the water inlet so as to allow the flushing cistern to fill.

Abstract: A device for detecting leaks and shutting off a water inlet into a main toilet flushing cistern in which the water inlet is controlled by a main valve which is closed by an operating lever, said main valve supplying the main cistern via a filling column, a float contained in a float compartment pivoting the operating lever when the main cistern is full. The float compartment is closed in its bottom part and over its entire lateral periphery so that the water contained in said float compartment can be expelled only by causing it to pass over at least one of the side walls thereof, and in that said device comprises an actuating mechanism for emptying said float compartment. The mechanism is configured to bring about the lowering of the float into said float compartment so as to cause the opening of the water inlet.
