Abstract
An integrated pressure regulator is provided with three stages configured to reduce an extreme tank pressure down to a typical working pressure. The regulator is configured to supply a steady working pressure until the tank pressure is reduced to little more than the working pressure itself. Stages of the pressure regulator are integrated into a body and arranged to minimize regulator mass and volume. A thermally-triggered pressure relief device may be included with a triggering time adapted to enhance the safety of smaller cylinders that may be used, e.g., in aerial applications.
