A liquid diffuser device comprises a support frame (2) with an upper tubular passageway (3) and a lower hollow body (4) defining a first longitudinal axis (L), a nozzle (5) associated with the passageway for directing a liquid jet longitudinally downwards at predetermined pressure and flow rate, a deflecting member (6) with a stem (7) held within the hollow body (4) and a deflecting plate (8) associated with the stem (7) and facing towards the nozzle (5) for deflecting the jet peripherally outwards and promoting the rotation (omega1) of the stem (7) about the first longitudinal axis (L) with a predetermined rotation speed, self-adjustment means (9) for adjusting the rotation speed of the stem, which comprise at least one elastomeric braking member (10) interposed between the stem (7) and the hollow body (4) for automatically adjusting the rotation speed of the stem (7) upon variation of pressure and flow rate of the liquid jet and for allowing even distribution of the diverted liquid. |
