A self-adjusting jet breaker (200) for impact sprinklers, including a spout (T) connected to a pressurized water supply line (L) by means of a rotary coupling (R); the spout is provided with a terminal nozzle (U) for generating a jet (G) and with an oscillating arm (B) which is provided with a baffle (D); the device is arranged on the oscillating arm and includes an active surface adapted to interact with the jet between two successive oscillations of the arm. The active surface of the device has an angle of inclination tau with respect to the longitudinal axis of the arm such as to be substantially tangent to the jet when downward transit through the jet from above begins and such as to be inclined during the entire downward transit and vice versa, so as to always receive an upward thrust (F). The device optimally distributes and breaks up the jet, and increases the beat frequency in an automatic manner, i.e. adapting to both high and low jet supply pressures. |
