摘要:
A sprinkler (10) head includes a sprinkler body (12) having an inlet bore (26) at one end, and a coupling element (38) at an opposite end adapted to connect the sprinkler body (12) to a water deflector plate . A multi-nozzle shuttle (14) supports at least two nozzles (16, 18) and is attached to the sprinkler body (12) axially between the inlet bore (26) and the coupling element for swinging pivotal movement between two nozzle-installed positions. The multi-nozzle shuttle (14) may also be provided with a shut-off surface portion (161) for shutting off flow through the sprinkler body (12) when the multi-nozzle shuttle (14) is moved to a shut-off position. The shuttle (14) may be moved manually or by a power actuator (182).
