ABSTRACT:
A hydraulic pressure-regulating system for a dual-functioning servo motor having a control valve device that permits direct manual operation of the servo motor output function up to a predetermined force whereupon servo assistance arises when the fingers of the input member take up a set lost motion and directly contact and mechanically operate the control pistons. A prestressed spring holds the pistons in a neutral position to maintain a desired initial pressure in the system.
