Abstract : The patent describes a closure device for installation in ventilation ducts of protective structures comprising a normally open valve plate mechanically connected to a piston which is blast actuated to pivot the valve plate to a closed position thus effectively sealing the device. A spring assembly maintains the valve plate in a scaled position once it is closed by the blast actuated piston.
