Abstract
A high stability pneumatic pressure regulator is provided by the use of a movable vane and nozzle assembly to operate a valve plug and thereby change the regulator output pressure. Movement of the vane and nozzle assembly is initiated by an adjustable input member which changes the vane to nozzle spacing and subsequently causes the vane and nozzle assembly to move with the valve plug until the normal vane to nozzle spacing is restored. A feedback of the output pressure is used to balance the adjustable input member.
