Abstract

See full text

A pendent-type fire protection sprinkler with a body defining an orifice and outlet for flow of fluid, and a deflector positioned coaxial with the outlet for impingement of fluid flow thereupon. The deflector has one or a combination of features for improved performance. For example, the deflector may have a frusto-conically shaped recess within a central area facing the sprinkler outlet, the recess defined by a surface slanted at a predetermined acute angle to the horizontal, with a plurality of holes or slots defined by the slanted surface, the recess being surrounded by an essentially flat outer area perpendicular to the sprinkler outlet axis. The deflector may have a bump, or other irregularity, on the sprinkler deflector inside surface opposed to the sprinkler outlet on each of the opposite tines in a plane perpendicular to a plane of the sprinkler frame arms. The deflector may have openings at about 45.degree. to the plane of the frame arms, the openings shaped with the width of each opening gradually decreasing towards the deflector periphery.
