Abstract
In the representative embodiments described in the specification, a pendent sprinkler has a sprinkler body with an axial passage for fire extinguishing liquid and a pair of frame arms supporting a deflector at a location spaced from the end of the axial passage. In order to provide high density water with uniform distribution throughout an area to be protected, the deflector is formed with a circumferential array of slots, each of which is oriented at an angle with respect to a radius line extending through the inner end of the slot. Preferably the angle of orientation of each slot is about 35.degree..
