A sprinkler apparatusfor providing more even coverage of a sprinkled area with water which is achieved by a different speed of rotation of a water deflectorrelative to a water diffuserin a wobbling sprinkler head. A diffuser headis rotatably attached to a baseand has a water diffuserfor diffusing water passing therethrough. A water deflectoris rotatably attached to the rotatable diffuser headfor directing water emitting from the nozzlethrough the water diffuser. A viscous fluid brakecouples the water deflectorto the water diffuserto vary the speed of rotation of the water diffuserrelative to the water deflectorto obtain a more even coverage of the area being sprinkled.

Sprinkler apparatus

A wobbling irrigation sprinkler head for attachment to a water conduit has a wobbling sprinkler head facing upward from the water supply conduit. The sprinkler head has a base having an attachment portion for attaching to a water source and a nozzle mounted to the base for directing water therethrough. A wobbling water deflector head is movably attached to the base and has a water deflector pad thereon having a deflector surface of predetermined shape to deflect water being emitted from the nozzle to rotate the wobbling water deflector head. A counterbalancing skirt extends from the water deflecting head around a portion of the base and spaced from the base for rotation with a wobbling water deflector head so that counterbalancing the skirt counterbalances the water deflector head to dampen vibration forces in the deflector head. The counterbalancing skirt flares from the water deflecting head adjacent to and surrounding the base and has a plurality of open areas therein and is positioned for the balancing point of the wobbling deflector head to be below the rotation point of the wobbling deflector head.

Wobbling sprinkler head

A wobbling sprinkler head has a sprinkler head main frame having a nozzle base having a nozzle therein and at least one arm extending therefrom supporting a deflector supporting base. The nozzle base is attached to a water supply and has a water inlet for directing water through the nozzle and against a water deflector head. The water deflector head has a shaft movably riding in the deflector supporting base and has a water deflecting surface attached to one end of the shaft and positioned to deflect water being emitted from the nozzle and a counterweight attached to the other end thereof to dampen vibrations. The water deflecting surface has a predetermined shape to cause rotation of the water deflector head responsive to water being directed thereagainst and has a protrusion extending therefrom to force an initial tilt and wobbling action.

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.
