Abstract
A sprinkler includes a riser, an impeller mounted in the riser, and a nozzle rotatably mounted at an upper end of the riser. A drive assembly including a reduction gear train couples the impeller and the nozzle. A friction clutch is located in the drive assembly between an output gear of the reduction gear train and an input gear of the reversing mechanism and provides a positive drive connection under a normal load and slips under an excessive load. An alternate embodiment utilizes the friction clutch in a rotor-type sprinkler in which the nozzle rotates continuously through a continuous 360 degree arc.
