Abstract

In the case of a pressure-worked automatic control system with a closed loop, and, more specially, a position automatic control system, the position of a servo-element is dependent on a spring placed between the servo-element or servo-motor and the sensing unit of the position automatic control system. The spring, placed between the servo-element or servo-motor and the sensing unit of the position automatic control system, is made up of at least one spiral spring, whose one end is able to be turned by a moving servo-part of the servo-element or servo-motor, while its other end is designed for acting on the sensing unit of the position automatic control system.
