Abstract

Directional sprinklers include a sprinkler body with a water directing structure configured to direct water passing from an outlet of the sprinkler body in one or more distinct and different directions. Water directing structures are disclosed in the form of deflectors having one or two separate water directing channels and hollow heads having at least two separate nozzles facing in two distinct and different directions. The channels and nozzles can be configured to direct water in diametrically opposing directions, mutually perpendicular directions or at any other desired orientation with respect to one another and to direct the water radially outwardly from the centerline of the sprinkler body outlet or at any predetermined transverse angle to that centerline. The throw of each channel and nozzle is longer than it is wide so that water is discharged over a generally rectangular or elliptical area in each direction. Different unidirectional and bidirectional downwardly discharging, upright sprinkler embodiments are disclosed particularly for use under pitched roofs, hipped roofs, dormers, interior cathedral ceilings and other pitched overhead interior walls.
