Abstract: A jet actuator, particularly for actuating hydraulic apparatus such as rotating pulse sprinklers, comprises a nozzle for generating a free jet of water directed along a first longitudinal axis, the nozzle being located at the free end of a spout, the spout being coupled to a line of pressurized water by means of a rotatable joint having a second rotation axis that is transverse to the first longitudinal axis. A deflector is provided which can freely oscillate in a transverse direction between a first end position wherein the deflector lies completely outside the jet and a second end position wherein the deflector is immersed to the maximum extent in the jet so as to draw part of its energy. A support is provided for oscillably mounting the deflector on the spout to transfer the energy drawn from the jet to the spout to promote a stepwise movement thereof about the second rotation axis.

Abstract: 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.

The joint includes a stationary lower portion that is in fluid communication with a pipe that delivers pressurized water to the sprinkler, and a moveable upper portion rotatably connected to the stationary lower portion about a substantially vertical axis. The moveable upper portion rotates in response to tangential forces that are applied by an impulse arm carried on a barrel from which pressurized water is discharged. The rate of rotation of the moveable upper portion is controlled by a braking mechanism that includes a pair of disks rigidly attached to the stationary lower portion and a pair of breaking elements mounted on the moveable upper portion.
