Abstract: A rotary nozzle sprinkler includes a base assembly with a bearing, a stem mounted rotatably in the bearing, and an elbow coupled at a proximal end to and rotatable with the stem and including an elbow bend. A nozzle is secured to a distal end of the elbow, and a diffuser assembly including a brake mechanism is cooperable with the elbow. By positioning the nozzle downstream of the elbow, the sprinkler can achieve a greater throw radius.

Abstract: A sprinkler head includes a sprinkler body formed with a through-bore defining a flow path adapted for alignment with a nozzle bore. A nozzle carrier is mounted on the sprinkler body for linear movement across the flow path and adapted to support plural nozzles. The nozzle carrier is configured to enable any one of the plural nozzles to be aligned with the flow path. The nozzle carrier is provided with plural discrete seal pads that are selectively movable into a position covering the flow path to thereby shut off flow through the sprinkler body.
