Abstract
A wall-controllable primary drive, for example a piezo actuator, guided in a first bore transfers its stroke motion-commutated onto a secondary-side lifter element guided in a second bore, transmitting said stroke by a piston-hydraulic stroke transmission on the basis of a hydraulic chamber. The pressure in a valve chamber is controlled via secondary-side lifter element.
