Abstract: A hydraulic system (1) for a switchable valve drive element (10) of an internal combustion engine (33) is provided and includes a throttled connection (13) created from a second channel (9), used to actuate a hydraulic play-compensation element (11) using hydraulic fluid, directly to an external radial side (12) of a coupling element (8). The coupling element (8) is supplied by a first channel (7) with the switching hydraulic pressure. These measures make it possible to keep the first channel (7) as free as possible of undesired air.
