    Abstract: In a motor vehicle camshaft adjusting device which comprises an open- and/or closed-loop control unit for adjusting the camshaft phase position in a normal operating mode to a temporarily intermittently constant phase position, the open- and/or closed loop control unit has an engine start operating mode in which the camshaft phase position is advanced during opening of the valve so as to provide a valve opening angle range which is smaller than a geometric normal opening angle range based on a crankshaft angle range.

    Abstract: A valvetrain for an internal combustion engine has a camshaft that can be rotated in a direction of rotation around an axis of rotation, at least two cam pieces arranged on the camshaft which each have at least two cams for actuating a respective gas exchange valve and which are rotationally fixedly connected to the camshaft, and an actuator via which the cam pieces can be shifted in the axial direction of the camshaft. A first of the cam pieces has a first rib protruding outwardly from a first base body of the first cam piece in the radial direction of the camshaft and the second cam piece has a second rib protruding outwardly from a second base body of the second cam piece in the radial direction of the camshaft.

    Abstract: A valve drive device, in particular for an internal combustion engine, includes a support element fixed to a housing and at least one axially shiftable cam unit allocated to a valve. The cam unit has at least three cam tracks. At least one switching unit which is a displacement body is provided to displace at least one part of the cam unit in the direction of a first actuation direction for axial shifting. The displacement body displaces at least one part of the cam unit in the direction of a second actuation direction opposing the first actuation direction.
