ABSTRACT:
An improved sprinkler nozzle comprises a nozzle body having a nozzle received in a recessed seat provided in a peripheral wall of the nozzle body. The nozzle is formed with a plurality of nozzle ports formed by the radially outer ends of a plurality of vertically flexible nozzle tubes. The flow volume of the water stream being thrown by the sprinkler nozzle is adjusted by selectively operating a flow volume adjustment member carried on the nozzle body to selectively open or close various of the nozzle tubes in various possible combinations. The flow volume of the nozzle will comprise the combined or aggregate flow volumes of the water sub-streams being thrown by those nozzle tubes that are left open. The trajectory of the water stream being thrown by the sprinkler nozzle is adjusted by selectively operating a trajectory adjustment member carried on the nozzle body to bend the flexible nozzle tubes about their vertically fixed, radial inner ends to raise and lower the radial outer ends of the nozzle tubes.
