ABSTRACT:
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.
