ABSTRACT:
An adjustable arc sprinkler nozzle comprises a lower nozzle piece which is relatively rigid and an upper nozzle piece which is made of a relatively flexible, compressible material. A plurality of radial channels are provided in the upper nozzle piece for forming radial streams out of water flowing into the lower nozzle piece. A deflector ring having pairs of spaced deflecting fingers can selectively compress the upper nozzle piece by pushing down on it adjacent either side of each channel near the radially outer ends thereof. This pinches off the channel area and simultaneously bends the channels down over the lower nozzle piece to decrease the throw radius while keeping the precipitation rate relatively constant.
