Abstract
A reaction drive sprinkler includes an improved drive assembly for rotating the sprinkler in steps about a water supply standpipe. The drive assembly comprises a fixed drive nozzle through which an inclined stream of irrigation water is projected for passage through a movable diverter tube mounted in front of the drive nozzle. The diverter tube is shifted by a reversing mechanism for slightly diverting the water stream for alternated interruption by a pair of laterally oppositely angled deflector spoons on a pivoting reaction drive arm. More particularly, the diverter tube directs the water stream for cyclic interruption by one of the deflector spoons to rotate the sprinkler stepwise in one direction through a selected arcuate path and then shifts the diverter tube to direct the water stream for interruption by the other deflector spoon for stepwise sprinkler rotation in the opposite direction.
