ABSTRACT:
A closure for a chamber having an interior which can contain a fluid under pressure provides apparatus for latching the door of the chamber in its closed position and locking it in that position when the positive pressure within the chamber reaches a predetermined level. The closure includes a door that is moved by positive pressure within the chamber and, through appropriate mechanisms, activates locking apparatus that prevents the door from leaving its closed position as long as such pressure is present within the chamber.
