The invention relates to a double-acting flushing valve arrangement, making alternative flushing possible after lavatory visits. With the invention, you may either flush part of the contents of the water tank or empty the whole water tank. The invention comprises an upper valve for flushing a small amount of water and a lower valve for flushing a large amount of water, said valves being arranged in a flushing valve housing located inside the water tank. The valve housing (1) consists of a hollow body having an upper orifice (13a) directed downwards for the upper valve (2a) and a lower opening (13b) directed upwards for the lower valve (2b). When the upper valve (2a) is open, the water flows up through the upper orifice (13a), through a duct (14) in the valve housing (1) and out to the discharge opening. When the lower valve (2b) is open, the water flows down through the lower orifice (13b) and out to the discharge opening. The valve housing is reversible to provide two openings having threads (12) of different diameters for connection to the water tank. |
