<p>A nutating sprinkler (10) includes a body portion (12) having a nozzle (N) at one end and a spray plate (28) supported thereon at an opposite end downstream of the nozzle (N). This spray plate (28) has a plurality of stream distributing grooves (30, 32) formed on one side thereof configured to cause the spray plate (28) to rotate when struck by a stream (S) emitted from the nozzle (N). The spray plate (28) also includes a flexible connector (42) coupling the spray plate (28) to a free end (50) of a first rigid shaft (52) seated in a housing (16) at the opposite end, such that the spray plate (28) is caused to wobble about a common center of motion as it rotates.</p> |
