  • Temperature-dependent pressure release device for pressure vessels
    Patent number: 4836443
    Abstract: Thermal expansion from the heating up of a pressure vessel in the form of elongated cylinder for containing a nuclear reaction is used to produce motion, beginning at a certain limit temperature, which is used to actuate a lever mechanism to open a safety valve which serves also for relief against overpressure. The thermal expansion of the pressure vessel itself may be used as the actuating force or an elongated rod-in-tube differential expansion device located between the pressure vessel and a nearby adjacent wall may be used to actuate the lever mechanism.
