Multi-nozzle shuttle for a sprinkler head

摘要

A sprinkler head includes a sprinkler body having an inlet bore at one end, and a coupling element at an opposite end adapted to connect the sprinkler body to a water deflector plate. A multi-nozzle shuttle supports at least two nozzles and is attached to the sprinkler body axially between the inlet bore and the coupling element for swinging pivotal movement between two nozzle-installed positions. The multi-nozzle shuttle may also be provided with a shut-off surface portion for shutting off flow through the sprinkler body when the multi-nozzle shuttle is moved to a shut-off position. The shuttle may be moved manually or by a power actuator.
