1. A system comprising:
an apparatus for regulating a gas pressure in an internal space of an airtight cabin that is used to accommodate living beings for transport in a flight craft;
a pressure vessel that stores gas containing oxygen at a pressure higher than atmospheric pressure; and
a constant flow valve that is attached to a first gas transfer path from the pressure vessel to the internal space of the cabin,
wherein
the apparatus includes a container and a moveable partition member that airtightly partitions an internal space of the container into a first space, which is open to the internal space of the cabin, and a second space, which is closed both to the internal space and an external space of the cabin,
the moveable partition member moves in the container under a force generated by a difference between a gas pressure in the first space and a gas pressure in the second space, and
as the moveable partition member moves, it opens and closes a second gas transfer path for flow of gas between the internal space of the cabin and the external space of the cabin.
