A control device for a toilet flush valve

摘要

A device control device for a flush valve in a toilet flush tank comprises two identical parts (1) each forming a vessel with an open cavity (9) with sides (5,7) and bottom (3). The device may act as a weight when the opening of the cavity (9) faces upward, whereby water may be contained in the cavity (9), or may act as a float when the opening of the cavity (9) faces downward, thereby trapping air in the cavity (9). Hereby is provided a device for retro-fitting a water saving control device in existing toilets with different control mechanisms. <IMAGE> <IMAGE>
