    Abstract: A controller having an integral element including two flexible diaphragms forming, with a casing, two separate chambers, one of the diaphragms having a larger pressure-subjected area than the other. One of the chambers is connected to a motivating source of fluid and the other is connected to a motivated source of fluid. A spring is connected to one of the diaphragms and the force of the spring is controlled.
