Abstract
A rotary drive sprinkler having a multiplicity of nozzles which can be selectively changed at any time. The nozzle assembly has an internal rotor member for bringing one of the nozzles into operation as the internal rotor is turned. A water flow can be directed from a rotor to a selected nozzle in a fixed circumferential row of nozzles to create a nozzle stream leaving the nozzle assembly, or a nozzle stream can be directed from a specific nozzle of a circumferential row of nozzles in an internal rotor to a single passage open to the exterior of the nozzle assembly.
