Abstract
A servo control for power-assisted steering for motor vehicles having two coaxial shaft parts that are positively coupled to each other, but with play. The shaft parts are coupled such that limited relative rotations between these shaft parts are possible against the resistance of a pretensioned spring arranged in between. These relative rotations cause a pivoting stroke of a lever arranged between the shaft parts, this lever thereby actuating the control spool of a servo valve.
