<p>Rotary nozzle for distributing a pressurized fluid in a duct, comprising a body of a cylindrical general shape (1) fixed at the end of a pipe (5) for supplying the liquid, and a piece (2) mounted in rotation on a sleeve (3) integral with a plug (4) screwed into the cylindrical body (1). The piece (2) comprises outlets (22) which rotate it when the fluid passes through, these outlets opening internally into an annular recess (21) interacting, furthermore, with at least one passage (33) to the internal channel, which passage is inclined radially with respect to this channel so as to create the circulation of the fluid in the opposite direction to the movement of the rotary piece. <IMAGE></p> |
