Abstract

A sprinkler assembly including a fluid deflecting structure including a plurality of spaced apart tines defining a plurality of slots. The tines include a first pair of symmetric tines and a second pair of symmetric tines disposed orthogonally to the first pair of symmetric tines. The tines includes outer edges of varying configuration to define tine and slot geometries and patterns.

and
a planar fluid deflecting structure supported by the frame arms, the fluid deflecting structure having a center aligned along the longitudinal sprinkler axis, a first peripheral edge defining a first diameter of the deflecting structure about the center, and a second peripheral edge defining a second diameter of the deflecting structure about the center, the second diameter being greater than the first diameter, the deflecting structure having a plurality of tines including:
a first symmetrical tine defining a first axis of symmetry disposed in the plane;
