Abstract (en)

[origin: WO2004016869A1] The present invention concerns an apparatus for dispensing a liquid, adapted to be placed in volume of liquid with fluctuating liquid level (59), particularly the cistern of a water closet. The apparatus is adapted to dispense liquid when the fluctuating liquid level (59) has been reduced a predetermined level and includes a hollow main body (1) with an upper end and a lower end. The upper end is air sealingly closed (5) and the lower end (1d) is open into the volume of liquid, and the main body (1) is adapted to contain a liquid column (58). A check valve (7) is provided at the upper end of the main body (1), and is adapted to allow pressure out of the cavity of the main body. A control channel (12) for controlling a pressure in the main body (1), controls when the liquid is to be dispensed in relation to the liquid level (59). The liquid volume has an upper end in fluid flowing contact with the cavity of the main body (1) and a lower end in fluid flowing contact with the liquid volume. Furthermore a method for final flushing of a closet bowl of a water closet with an apparatus according to the invention is described.
