Abstract (en)
The device comprises an inner chamber (10) having a liquid exit (11), with a nozzle (20) positioned in the chamber (10) and traversed, for liquid passage, by an axial conduit (21) having a front portion (22) positioned in correspondence with and closing the exit, and a rear portion (23) arranged to roll on the surface (12) of the chamber (10). To the nozzle (20) there is joined a cap (23) of circular section, coaxial with the conduit (21) and communicating with it, its concavity facing upstream, to define the rear portion of the nozzle (20); a second nozzle (30) is positioned upstream of the first nozzle (20) and is arranged to rotate about the device axis (A) to emit a liquid jet directed against the inner surface of the cap (23) in a direction having at least one component radial to this surface; the second nozzle (30) is associated with means (32) for rotating it by the energy possessed by the liquid. <IMAGE>
