The governor of the invention consists of an output solenoid having a plunger operatively connected to the mechanism to be controlled. The output solenoid is a “bang-bang”type such that full power or no power is delivered to the solenoid even for small errors between the desired operating condition and actual condition of the mechanism to be controlled. The output solenoid is connected in a hydraulic circuit with a control solenoid having a control valve such that the movement of the fluid through this circuit is regulated by the control solenoid. The co...


An electro-hydraulic governor for controlling operation of on external device comprising; (a) an electronically operated actuator having a movable member where the position of the member controls said external device, said electronically operated actuator being located in a hydraulic circuit; (b) a control valve connected in the hydraulic circuit with said actuator for controlling the rate of movement of said member, and for locking it against movement when correctly positioned; (c) control means for comparing actual condition against desired condition a...
