High load breakable glass bulb heat responsive link

Patented mechanical system of fire detection by liquid filled glass bulb breaking. In case of fire, when the temperature reaches the liquid boiling temperature, it causes the explosion of the glass bulb, which releases the mechanism. This self-powered mechanism does  not require  power  supply such as electricity or compressed  air. It i  can open smoke vents, skylights in buildings,  but also actuate fire doors, air conditioning  dampers, store curtains, inflammable gas or liquid valves, range hood exhausts, paint and solvent exhaust fans and dampers, etc.
