An Emergency Pressurization System for an Escape Capsule was developed. It included its own "bottled" high pressure air supply and a sequential system of controls whereby, after being armed either manually or by separation from the air-craft, the system automatically (as a result of the sensing of the drop of cock-pit pressure) releases its air at the rate required for fast repressurization. It then cuts short the fast repressurization as soon as the capsule pressure has again returned to a safe level, and directs the air through an absolute pressure regulator which maintains this level, compensating for capsule leakage.
