Abstract

An air pressure regulator includes a cylindrical rotor with a hollow interior. The thin walls of the rotor have windows which overlap inlet and exhaust windows in the housing. The rotor is rotated progressively by a stepper motor in response to computer determination of required pressure. The system is used to inflate a pilot's anti-G suit.
