A device (100,100') for actuating at least one valve (4, 5) in an internal combustion engine (2, 2'), wherein the device comprises - a camshaft arrangement (200,200') comprising ∘ a hollow outer shaft, ∘ an inner shaft, which is concentrically mounted inside of the outer shaft to be pivotable relative to the outer shaft, ∘ a first cam lobe mounted on one of the inner shaft and the outer shaft in a rotationally fixed manner, ∘ a second cam lobe mounted on the other of the inner shaft and the outer shaft in a rotationally fixed manner, - a rocker arm arrangement (300,300') comprising ∘ a first primary rocker arm, which is arranged to follow the first cam lobe and arranged to actuate a first valve when it follows the first cam lobe, characterized in that the rocker arm arrangement further comprises ∘ an auxiliary rocker arm, which is arranged to follow the second cam lobe and that the auxiliary rocker arm is adapted to actuate the first primary rocker arm so that an opening time of the first valve may be extended by the auxiliary rocker arm following the second cam lobe, wherein the first cam lobe and the second cam lobe have different cam profiles, and in that the device comprises a damping arrangement for damping a transition at a transfer point, at which a change of valve opening actuation takes place between the first cam lobe and the second cam lobe, for achieving a smooth transition between valve actuation controlled by the first cam lobe and the second cam lobe. - a camshaft arrangement (200,200') comprising ∘ a hollow outer shaft, ∘ an inner shaft, which is concentrically mounted inside of the outer shaft to be pivotable relative to the outer shaft, ∘ a first cam lobe mounted on one of the inner shaft and the outer shaft in a rotationally fixed manner, ∘ a second cam lobe mounted on the other of the inner shaft and the outer shaft in a rotationally fixed manner, ∘ a hollow outer shaft, ∘ an inner shaft, which is concentrically mounted inside of the outer shaft to be pivotable relative to the outer shaft, ∘ a first cam lobe mounted on one of the inner shaft and the outer shaft in a rotationally fixed manner, ∘ a second cam lobe mounted on the other of the inner shaft and the outer shaft in a rotationally fixed manner, - a rocker arm arrangement (300,300') comprising ∘ a first primary rocker arm, which is arranged to follow the first cam lobe and arranged to actuate a first valve when it follows the first cam lobe, characterized in that the rocker arm arrangement further comprises ∘ an auxiliary rocker arm, which is arranged to follow the second cam lobe and that the auxiliary rocker arm is adapted to actuate the first primary rocker arm so that an opening time of the first valve may be extended by the auxiliary rocker arm following the second cam lobe, wherein the first cam lobe and the second cam lobe have different cam profiles, and in that the device comprises a damping arrangement for damping a transition at a transfer point, at which a change of valve opening actuation takes place between the first cam lobe and the second cam lobe, for achieving a smooth transition between valve actuation controlled by the first cam lobe and the second cam lobe. ∘ a first primary rocker arm, which is arranged to follow the first cam lobe and arranged to actuate a first valve when it follows the first cam lobe, characterized in that the rocker arm arrangement further comprises ∘ an auxiliary rocker arm, which is arranged to follow the second cam lobe and that the auxiliary rocker arm is adapted to actuate the first primary rocker arm so that an opening time of the first valve may be extended by the auxiliary rocker arm following the second cam lobe, wherein
