<p>A sprinkler device is described, for fire extinguishing systems, apt to be coupled with a fluid supply line and placed in an environment which has to be protected from a fire. The device (1) comprises actuation means (13) being sensitive to the room temperature, which are apt to determine the motion of shutter means (8-12) for allowing the outflow of the fluid to an outlet (4), when a determined room temperature threshold is exceeded. Such actuation means (13) comprise an unbreakable container defining an internal cavity for containing a material whose volume increases or decreases in function of the temperature of said container, said temperature being directly determined by the room temperature, a shaft (17) being movable in function of the volume increase or decrease of said material, closure and sealing means for said cavity and said shaft (17).</p> |
