ABSTRACT:
An electrically controlled modulating pressure regulator in which a main valve regulates fluid flow between an inlet and an outlet in response to a control pressure produced by a servo valve which is responsive to the outlet pressure and the force applied by a regulator spring to a diaphragm carrying the servo valve closure element. Deformation of the regulator spring can be varied by an electrical actuator in the form of a wire segment of a shape memory alloy through which electric current can be passed to vary its temperature and length.
