Abstract
A sprinkler device for fire extinguishing systems is adapted to be coupled to a fluid supply line and placed in an environment which is to be protected from fire. The device has an actuator sensitive to room temperature which causes motion of a shutter for controlling the flow of the fluid to an outlet when the room temperature exceeds a predetermined threshold. The actuation device has an unbreakable container in which there is stored a material having a volume which is a function of the container's temperature, a shaft movable in response to a change in volume of the material, and a closure and sealing device for the chamber and shaft.
