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 distribute fire extinguishing liquid substantially uniformly throughout a protected area, the deflector is provided with pairs of tines having ends which are oppositely inclined with respect to the plane of the central portion of the deflector and which extend upwardly from that plane and has further tines intersected by the plane of the sprinkler arms with end portions which are displaced downwardly from the plane of the central portion of the deflector and are inclined upwardly with respect to that plane.
