Patent ID: 8584969

Claim:
A liquid diffuser device, comprising: a support frame connectable to a liquid feeding pipe, said support frame having an upper tubular passageway for a liquid and a lower hollow body both defining a first longitudinal axis; a nozzle associated to said upper passageway of said support frame for directing longitudinally downwardly a liquid jet having predetermined pressure and flow rate; a deflecting member with a lower stem defining a second longitudinal axis, said stem being fastened to said hollow body to allow rotation of said second longitudinal axis about said first longitudinal axis; an upper deflecting plate associated to said stem and faced to said nozzle for deflecting peripherally outwardly the liquid and promoting the rotation of said longitudinal second axis about said first longitudinal axis and the rotation of said stem about said second longitudinal axis with respective predetermined rotation speeds; and self-adjustment means for adjusting the rotation speed of said stem and of said second axis; wherein said self-adjustment means comprise at least one elastomeric braking member interposed between at least an upper portion of said stem and said hollow body for automatically adjusting the rotation speeds of said stem and of said second longitudinal axis upon variation of pressure and flow rate of the liquid jet and for providing an even distribution of the deflected liquid wherein said deflecting plate has a lower tubular portion extending therefrom and surrounding said stem, said lower portion being at least partially housed into said hollow body.
