Abstract
A hydraulic actuating device () for an automotive friction clutch (), has a master cylinder () whose master piston () can be impinged upon with a master force (F) via an actuating mechanism () and can be displaced by a master travel (S), and a slave cylinder () with a slave piston () which is hydraulically connected in series to the master piston via a liquid column and is functionally linked with a clutch-release member () of the automotive friction clutch. The actuating device may be provided with an adjusting unit () may have an adjusting piston (). The adjusting piston is hydraulically connected in series to the master piston and can be impinged upon with a force and displaced via a transmission () that is driven by an electric motor. The actuating device further has a control unit (C) which is used to control the adjusting unit especially subject to a master variable (F; S).
