PCT No. PCT/EP91/01324 Sec. 371 Date Feb. 19, 1993 Sec. 102(e) Date Feb. 19, 1993 PCT Filed Jul. 15, 1991 PCT Pub. No. WO92/03230 PCT Pub. Date Mar. 5, 1992.A rotating impact sprinkler comprising a device for connecting the pressurized water column to a rotating joint which supports a rotating assembly which is formed by a tubular body with a nozzle for generating a jet, an oscillating arm and deflection element mounted at the end of the arm so as to interact with the jet. The deflection element comprises at least one main deflector which oscillates elastically in a direction which is transverse to the arm between a central equilibrium position, in which the surface effected by the jet is minimal, and at least one lateral abutment position, in which the surface effected by the jet is maximal. The change from the minimally effected surface to the maximal one is sudden, so as to instantly increase withdrawal of energy from the jet and generate impulsive forces on the deflector.
