It interacts with a camshaft and a control shaft. The control device is actuated by a hydraulic medium and has a first control element and a second control element movable relative to one another. The first control element is sleeve-shaped and the second control element is received in the first control element. A rocker lever is acted on by the camshaft. The first control element is supported on the rocker lever and the second control element is supported on the control shaft.
