Abstract
In an actuating drive for valves, the stroke motion of the servo piston has to be transmitted to the return sleeve in the control block, so that this results in that hydraulic feedback which restores the equilibrium at the servo piston. By means of a lever or a single-point mounting, this same stroke motion is directly transmitted to a pin attached in an eccentric position relative to the center axis of the return sleeve and transmitted from this pin to the return sleeve adjoining thereunder.
