<p>A camshaft assembly, comprising a camshaft (2) having a receiving space (6) in an interior thereof, at least some sections of the assembly being made of a magnetizable material, and an electromagnetic actuating unit (4) for actuating an actuating partner (5), comprising a control valve of a camshaft adjuster (3), a coil winding (8) and an armature (7) for cooperating with the actuating partner (5), the armature being adjustable by energizing the coil winding (8). The armature (7) is arranged at least in some sections, preferably completely, inside the camshaft (2) in the receiving space (6) and the coil winding (8) for the non-contact adjustment of the armature (7) is arranged radially outside the camshaft (2), and the camshaft (2) has a first axial section (9) and a second axial section (10), between which a material region (11) influencing the magnetic flow (12) is provided in order to increase the magnetic flow (12) from one of the axial sections (9, 10) to the respective other axial section (9, 10) via the armature (7).</p> |
