ABSTRACT:
A sprinkler apparatus has a nozzle of a cross-sectional configuration to provide a liquid jet of similar cross-sectional configuration which impacts a reflector surface to reflect a spray of a cross-sectional configuration similar to that of an area to be sprayed. The nozzle passage and reflector surface may preferably be defined on a unitary nozzle device mounted on a base.
