Abstract

An arrangement for carrying out a two-stage linear movement with a stationary and a movable constructional unit, comprises a hydraulic cylinder and an hydraulic piston preferably in the form of a plunger. The hydraulic piston has a hollow volume which houses a plunger piston which, in turn, rests on a spindle rotated by a servomotor in the movable construct-ional unit. The plunger piston can be displaced axially in the hydraulic piston and also in the hydraulic cylinder by use of the spindle.
