  • Silent-operating device for feeding water into a tank, in particular for filling a lavatory flush tank
    Patent number: 6848668
    Abstract: 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 housing flow deflecting members; the members are perforated members arranged successively and spaced apart in the flow direction inside the chamber, and have respective numbers of through holes; 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.

  • Lavatory flush tank silent-operating fill device
    Patent number: 6810904
    Abstract: A lavatory flush tank silent-operating fill device has a silencer extending along an axis and through which a stream of water flows; a number of channels are defined inside the silencer by a bundle of substantially straight, parallel tubes housed inside the silencer and parallel to the axis, and into which the stream of water is divided; and the flow section of the channels is such that flow of the water inside is substantially laminar.
