A sprinkler assembly comprising: a body including a passageway, an inlet opening , a discharge opening , and an axis extending through said discharge opening , wherein water delivered to said passageway flows as a column of fluid from said discharge opening , said column of fluid having a diameter generally equal to a diameter of said discharge opening ; a support extending from said body ; an upper flow-shaper member supported by said support for shaping the flow of fluid from said discharge opening , the upper flow-shaper member being located at an opening of said support , said upper flow-shaper member having a shelf portion having a proximal end and a distal end with said proximal end being located closer to said discharge opening than said distal end, wherein said shelf portion extends from said support at said proximal end and being generally parallel to and spaced from said axis , a shield extending directly from said distal end of said shelf portion and generally perpendicular to said shelf portion and said axis and partially intersecting said column of fluid, wherein, the sprinkler assembly further comprises a lower flow shaper extending from said support on an opposite side of said axis from said upper flow shaper member and partially intersecting said column of fluid without any obstruction of said column of fluid between said opening in said support and said lower flow shaper , characterized in that said shelf portion and said shield each having a width greater than the diameter of said opening in said support and wherein said distal end of the upper flow shaper extends along the axis by at least 30 percent further than the lower flow shaper . a body including a passageway, an inlet opening , a discharge opening , and an axis extending through said discharge opening , wherein water delivered to said passageway flows as a column of fluid from said discharge opening , said column of fluid having a diameter generally equal to a diameter of said discharge opening ; a support extending from said body ; an upper flow-shaper member supported by said support for shaping the flow of fluid from said discharge opening , the upper flow-shaper member being located at an opening of said support , said upper flow-shaper member having a shelf portion having a proximal end and a distal end with said proximal end being located closer to said discharge opening than said distal end, wherein said shelf portion extends from said support at said proximal end and being generally parallel to and spaced from said axis , a shield extending directly from said distal end of said shelf portion and generally perpendicular to said shelf portion and said axis and partially intersecting said column of fluid, wherein, the sprinkler assembly further comprises a lower flow shaper extending from said support on an opposite side of said axis from said upper flow shaper member and partially intersecting said column of fluid without any obstruction of said column of fluid between said opening in said support and said lower flow shaper , characterized in that said shelf portion and said shield each having a width greater than the diameter of said opening in said support and wherein said distal end of the upper flow shaper extends along the axis by at least 30 percent further than the lower flow shaper . <EOS>
