Abstract: The invention relates to a cistern, in particular an in-wall cistern, for a toilet or urinal, with a drain valve which has a closure body which can be lifted from a closed position into a flushing position. The closure body is designed as an overflow pipe and has a seal which rests tightly on a valve seat in the closed position, with at least one water intake line, with a valve assembly for letting in drinking water present in the water intake line, with a water discharge line for discharging the drinking water let in by the valve assembly, and with a controller which generates a control signal for actuating the valve assembly as a function of a sensor signal and/or when a predefined time interval has been exceeded.

The valve assembly lets in water from the water intake line as a function of the control signal.

Abstract: A valve fitting for filling a sanitary cistern includes a connection element, a shutoff valve including an actuation element, and a float-actuated filling valve. The connection element, shutoff valve and filling valve are interconnected to form a water passage into the cistern. A float is connected to the filling valve. The actuation element of the shutoff valve is rotatable about a rotational axis when the float is in the operating position thereof, the shutoff valve being operationally usable in the valve fitting in at least two different positions, the connection element configured to be mounted at an opening in the left-hand cistern side wall in one of the positions, and at an opening in the right-hand cistern side wall in another of the positions, and the actuation element being accessible from the front of the valve fitting in the at least two positions of the shutoff valve.

Abstract: The invention relates to a drain valve for a sanitary flushing cistern, in particular a flush-mounted flushing cistern, including a valve housing and a valve body guided in the valve housing and configured as an overflow pipe having a seal assigned to a valve seat, wherein the valve body is provided with at least one pull tab for lifting the valve body, and one buoyant body.
