Abstract (en)
A dosing device (5) for dosing a service liquid in a water stream discharged from a flushing tank, comprises: a reservoir (21) for a service liquid; a dosing chamber (22) communicating with the reservoir (21) for receiving a dose of service liquid from the reservoir (21) through an opening (30); a movable piston (23) housed in the dosing chamber (22) and operated by an expandable bellows (24); a water supply pipe (25), connectable to a filling valve (3) of the tank (1) for feeding water to the bellows (24) so as to expand the bellows (24) and consequently move the piston (23) in the chamber and push service liquid from the dosing chamber (22) into a delivery pipe (26) of service liquid connectable to an overflow pipe (15) of the tank (1).
