ABSTRACT:
A steering control with a hydraulic follow-up wherein a movable valve member of a control valve is automatically brought back to a nonsteering disposition as a result of the movement of the device being steered to the desired steering position. Movement of the device is effected by a pair of steering cylinders. Control of the movable valve member is effected by a variable volume storage device which receives hydraulic fluid from the control valve and returns the fluid to the control valve as a function of the relationship of the steering mechanism and device to be steered.
