ABSTRACT:
A rotary sprinkler head comprising a sprinkler body having an outlet defined by a selected nozzle for directing water under pressure communicated therewith into an atmospheric condition in a primary stream having a generally vertically extending axis. A rotary distributor is mounted for rotational movement about a generally vertical rotational axis with respect to said sprinkler body in engaging relation with respect to the primary stream directed from said nozzle so as to be rotated thereby. A speed reducer is provided to slow the rotational speed imparted to the distributor. The distributor has surfaces for directing the primary stream outwardly in such a way as to create reactionary forces having net components acting tangentially to the axis of rotation of the distributor which do not increase substantially with increases in flow rates under constant pressure conditions thereby enabling the distributor to operate with a relatively narrow range of rotational speed changes within a relatively wide range of nozzle size changes.
