Abstract
A valve within an oxygen breathing apparatus (OBA) simulator to simulate the loss of oxygen supply that occurs in an operational OBA when the user accidentally deflates the bag(s), such as by impact. The valve is within the tubular conduit inside the simulator's airbag and is held in its open position when the airbag is inflated by a cord attached to the inner surface of the bag, but is spring loaded to close and block the oxygen path through the conduit when the attachment cord is slackened.
