A dry sprinkler assembly includes a housing, a sprinkler head assembly having a sprinkler head and a trigger assembly, which is in fluid communication with the fluid flow passage of the housing, and an actuator assembly. The trigger assembly substantially closes the outlet opening of the sprinkler head and releases the closure during a fire condition. The actuator assembly includes a sealing subassembly, which seals the inlet port of the housing and is operatively coupled to the trigger assembly such that the sealing subassembly releases the scaling of the inlet port in response to the trigger assembly releasing the closure at the outlet opening of the sprinkler head. Furthermore, the sealing subassembly moves in a linear path substantially parallel with the central longitudinal axis of the housing when releasing the scaling of the inlet port wherein the flow of fire suppressant through the inlet port and into the fluid flow passage of the housing is substantially unimpeded.

Ensemble sprinkleur sec comprenant un corps, un ensemble d'arrosage comportant une tête d'arrosage, et un ensemble de déclenchement en communication avec un passage de fluide du corps, et un ensemble d'actionnement. L'ensemble de déclenchement maintient l'ouverture de la tête d'arrosage sensiblement fermée et la dégage en cas d'incendie. L'ensemble d'actionnement comprend un sous-ensemble d'étanchéité qui bouche l'orifice de sortie du corps et qui est relié fonctionnellement à l'ensemble de déclenchement de telle sorte que l'ensemble d'étanchéité libère l'orifice intérieur lorsque l'ensemble de déclenchement relâche le bouchon de l'ouverture de la tête d'arrosage du sprinkleur. De plus, le sous-ensemble d'étanchéité se déplace sur une trajectoire linéaire sensiblement parallèle à l'axe longitudinal du corps quand l'orifice d'entrée est dégagé de façon que l'agent d'extinction puisse s'écouler par l'orifice d'entrée et le passage de fluide du corps sans obstructions appréciables.
