Silent-operating device for feeding water into a tank, in particular for filling a lavatory flush tank

摘要

There is provided a silent-operating device for feeding water into a tank, in particular for filling a lavatory flush tank; the silencing effect is achieved by feeding the water through a chamber (20) housing flow deflecting members (25); the members (25) are perforated members arranged successively and spaced apart in the flow direction (23) inside the chamber, and have respective numbers of through holes (26); the holes of consecutive members being offset with respect to one another to define a labyrinth path, i.e. a number of winding coil-like or zigzag paths, inside the chamber.
