  • Servo-operated regulator valve
    Patent number: 4077431
    Abstract: A servo-operated fluid flow control valve includes a valve body housing a main valve which defines with the body an inlet chamber, an exhaust chamber, and a control chamber. An auxiliary valve is interposed between the control and exhaust chambers and is movable relative to the main valve by a jack controlled by a regulator. The arrangement is such that when the auxiliary valve is closed, the inlet and control chambers are in communication, and when the auxiliary valve is open, the control and exhaust chambers are in communication while the inlet and control chambers are isolated from each other.
