Abstract
To vent the contents of a pressure vessel upon failure of the vessel due to overheating or to abnormal pressure increase therein, a safety valve defines two passages through it both leading from the vessel interior to atmosphere. One passage is normally obstructed by a fusible member; the other is normally obstructed by a rupturable disc or like member.
