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°.

Dans les améliorations décrites dans la spécification, un extincteur automatique en position vers le bas possède un corps pourvu d'un passage axial pour le fluide d'extinction d'incendie et deux bras de cadre supportant un déflecteur à un emplacement espacé de l'extrémité du passage axial. Pour fournir une forte densité d'eau répartie uniformément sur la surface à protéger, le déflecteur comporte une série de fentes sur sa circonférence, chacune d'elles est orientée selon un angle par rapport à une ligne radiale qui passe par l'extrémité intérieure de la fente. De préférence, l'angle d'orientation de chaque fente est d'environ 35 degrés.
