Camshaft adjustment device

The camshaft adjuster according to wherein all tappet longitudinal centre axes (A1, A2, A3) are spaced from the camshaft axis of rotation (D) in the plane.

The camshaft adjuster according to each tappet longitudinal centre axis (A1, A2, A3) defines a tappet plane which is perpendicularly penetrated by the camshaft axis of rotation (D), and wherein the spacing measured in the direction of the longitudinal extension of the camshaft axis of rotation (D) between each two adjacent ones of the tappet planes is the same in the case of each adjacent tappet planes.

A camshaft adjuster (3), comprising a camshaft axis of rotation (D) and an electromagnetic tappet actuating device (4) having at least one electromagnetic drive unit, which for exerting an actuating force on a corresponding elongated tappet unit (9, 10, 11) defining a tappet longitudinal centre axis (A1, A2, A3) arranged perpendicularly to the camshaft axis of rotation (D) and activatable, in order to engage with the at least one tappet unit (9, 10, 11) in a shifting groove (8) of an adjustable cam piece (7), wherein the drive unit, on a facing acting end on the associated tappet units (9, 10, 11), forms an acting surface that is moveable in an actuating direction of the drive unit and an end face on the acting side facing away from the respective associated shifting groove (8) of the tappet unit (9, 10, 11) interacts with the acting surface, wherein the tappet unit (9, 10, 11) is arranged relative to the camshaft axis of rotation (D) in such a manner that its tappet longitudinal centre axis (A1, A2, A3) is spaced from the camshaft axis of rotation (D) in a plane (E) receiving the camshaft axis of rotation (D) and running perpendicularly to the tappet longitudinal centre axes (A1, A2, A3).
