A hydraulically actuated, preferably variable, valve drive of an internal-combustion engine is provided, with a slave unit ( 15 ), which is embodied as a separate component relative to a master unit. A special characteristic is that the slave unit is provided with a hydraulic backlash compensation element ( 9 ), which is connected to a path ( 12 ) for feeding hydraulic medium only outside of a stroke phase of a slave piston ( 5 ). As a result, on one hand an easy-to-produce valve drive with slave unit ( 15 ) is provided. On the other hand, unnecessary "pumping up" of the backlash compensation element ( 9 ) during the stroke phases of the slave piston ( 5 ) is prevented by the previously mentioned admission of hydraulic medium.
