1. A device for aerating a jet of water, comprising a substantially cylindrical wall defining an inner mixing chamber and a bottom delivery orifice, air intake openings traversing said cylindrical wall, means for jet regularization arranged within said delivery orifice, and at the upper end of said cylindrical wall a pulverization device comprising a first element having at least one ring series of openings and a second element also having at least one ring series of openings, said second element being superimposed onto said first element with the openings of said second element in register with the openings of said first element only along short portions adjacent the edges of the openings, whereby the openings of said first and second element together form restricted passages for water, whose cross section is substantially lesser than the cross section of the openings themselves, said restricted passages being formed between the opposite edges of each opening of each element and the contiguous edges of two subsequent openings of the other element, whereby each pair of subsequent restricted passages generates two small water jets slanting the one towards the other.
