A first embodiment employs a rotatable nozzle assembly that is dimensioned and arranged to spin as it receives a stream of liquid via the conduit. The nozzle assembly ejects a stream of liquid as it spins to thereby obtain a helical “tornado” flow pattern. In a second embodiment, a fixed or movable deflector is used so that water exiting a nozzle strikes a surface of the deflector to thereby develop a “wave” or “hard rain” discharge pattern. Multiple modes of operation are also contemplated.

Abstract: A rotary sprinkler (10) including a water inlet, a water outlet arranged for rotation about a rotation axis (14), a water director associated with the water outlet and a watering pattern determiner associated with at least one of the water outlets and the water director. The sprinkler (10) operates to cause the sprinkler (10) to have a substantially non-repeated watering pattern extending over more than 360 degrees about the rotation axis. The watering pattern is asymmetric with respect to the rotation axis (14) and is rotated for each successive rotation of the water outlet about the rotation axis (14) with respect to the watering pattern of the preceding rotation by a predetermined amount, whereby the successive rotations increase the angular uniformity of watering about the rotation axis.

Abstract: An irrigation sprinkler with two viscous brakes. The viscous brakes work in conjunction with each other to maintain a low RPM and also to rotate a water stream diffuser. The water stream is first directed toward a deflector that offsets the stream and angles it toward the area to be watered. The offset stream applies a torsional force on the deflector causing it to rotate. The stream is then interrupted intermittently by the diffuser that is rotating at a different RPM. The end result is a sprinkler that rotates slowly and breaks up the stream of water intermittently to create an even pattern of water on the area being sprinkled without using mechanical parts, such as ratchets or gearing. This is desirable for smooth operation and less chance of the operation being interrupted from contamination by dirt, insects, debris, etc. Also, a more random diffusion of the water is obtained.

Abstract: The present invention provides an apparatus with a moving nozzle that delivers fluid in a wobbling, rotating or oscillating pattern. The movement of the nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the nozzle to wobble or rotate. The moving nozzle can be used as a motor providing a rotating output shaft or ring.
