Abstract

En lufttrykk-regulator omfatter en sylinderformet rotor med et hult indre. De tynne veggene av rotoren har vinduer som overlapper innløps- og eksosvinduer i huset. Rotoren blir rotert progressivt av en trinnmotor i respons på en data-maskin-bestemmelse av nødvendig trykk. Systemet brukes til å pumpe opp en pilots anti-G-drakt.
