A self adjusting jet breaker device for impact sprinklers having a spout connected to a pressurized water supply line using a rotary coupling, a terminal nozzle for generating a water jet, and an oscillating arm having a baffle. The device is arranged on the oscillating arm and includes an active surface adapted to interact with the water jet between two successive oscillations of the arm. The active surface of the device has an angle of inclination with respect to a longitudinal axis of the arm such as to be substantially tangent to the water jet as the first surface moves downward from above. The angle of inclination increases during the entire downward transit and decreases during an upward transit, so as to always receive an upward thrust from the water jet. The device optimally distributes and breaks up the jet, and increases the beat frequency of oscillations of the arm in an automatic manner, i.e. adapting to both high and low jet supply pressures.
