Abstract
An in-line air pressure regulator for scuba diving is designed to augment an independent air supply system in the event of a failure of the primary pressure regulator. The in-line air pressure regulator comprises a small, encapsulated, spring-biased valve which is designed to reduce tank pressure to a level which is compatible with the spare, or backup, second stage regulator. In effect, it is a simplified auxiliary primary air pressure regulator.
