1. A sprinkler comprising:
a support structure;
a nozzle engaged to the support structure and having a first inlet and a first outlet connected by a first lumen; and
a baffle pivoted to the support structure and facing the nozzle,
wherein the first outlet of the nozzle has a smaller cross-sectional area than the first inlet, and
wherein a perimeter of the first lumen at the first outlet is non-circular and comprises an arched portion and a straight portion,
further comprising a second lumen having a second inlet and a second outlet, the first and the second inlets receiving a fluid from a same portion of the sprinkler, the first and the second outlets facing the baffle,
wherein the second lumen is connected to an input manifold, wherein the input manifold is connected to a drive system that causes a pivoting of the baffle, and wherein a fluid traveling through the second lumen generates a negative pressure that causes the drive system to pivot the baffle.
