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.

An impact sprinkler with a removable self-adjusting jet breaker device, the impact sprinkler comprising: a water spout having a fixed end that connects to a pressurized water pipe by means of a rotatable joint with a first rotation axis and having a second end; a nozzle arranged at the second end of said spout for generating a water jet; a swingable arm with a longitudinal axis mounted for oscillation about a second axis substantially perpendicular to said first rotation axis; a water deflector, mounted to said swingable arm at a first transverse distance from said second axis, that cyclically interacts with the water jet, said water deflector deflecting the water jet to thereby cause oscillation of said arm from a starting position and breaking up the water jet to cause said swingable arm to move back toward the starting position, wherein said water deflector extends to a maximum height, measured from the longitudinal axis, equal to a first value; a jet breaker device removably mounted to said swingable arm at a second transverse distance from said second axis, wherein said second distance is less than said first distance; wherein said jet breaker device has at least one first active surface longitudinally spaced from said water deflector to interact with said water jet between successive oscillations of said swingable arm; wherein said first active surface forms an inclination angle with respect to said longitudinal axis such that said first active surface is substantially tangent to the water jet when said first active surface starts to interact with the water jet; wherein said first active surface extends to a maximum height measured from said longitudinal axis, equal to a second value that is greater than said first value so that said first active surface interacts with the water jet after the water jet no longer interacts with said water deflector during oscillation of the swingable arm.
