Abstract
A rotary sprinkler includes a rotor rotatably mounted with respect to a nozzle to be impinged and to be rotated by the water jet from the nozzle, and a sleeve circumscribing the nozzle and formed with an open end through which the water jet is discharged laterally of the nozzle. The rotor is displaceable axially of the nozzle. A spring normally urges a closure-surface of the rotor against the open end of the sleeve to close it against the entry of foreign matter, but is deformable by the water jet to displace the closure surface of the rotor axially away from the sleeve.
