Deflector comprises hub with slot and orifice. Sprinkler also includes heat-sensitive member formed of shape-memory material. Bush with through slot fixed with locking member is installed in the orifice so that bush may perform axial movement. Locking member is simultaneously secured inside hub and bush. Locking member includes mounting pin bushing extending tangentially inside bush having through slot and in hub orifice so that pin may spin. Pin has groove with depth equal to half of pin diameter and length exceeding bush slot length. Heat-sensitive member is braid having the first end secured in mounting pin bushing and the second one connected to deflector perimeter from side opposite to thrust means location.EFFECT: simplified structure along with provision of necessary response speed.2 cl, 9 dwg
