It relates to a valve actuating device (4) for variable valve control, wherein at least one articulation point (16, 18) between the valve lever (9) and the gas exchange valve (2, 3) or a force transmission element which acts on the gas exchange valve (2, 3) is configured so as to be adjustable via an adjusting device. In order to make jolt-free valve actuation possible, it is proposed that the adjusting device has a piston (13) which is mounted displaceably in the valve lever (9) and adjoins a pressure chamber (19, 20), wherein a piston rod (15) which is connected to the piston (13) is connected in an articulated manner at a first articulation point (16) to a first end of a push rod (17), the second end of which is connected in an articulated manner at a second articulation point (18) to the gas exchange valve (2, 3) or the force transmission part which acts on the gas exchange valve (2, 3), with the result that the first articulation point (16) can be displaced in the longitudinal direction of the piston rod (15) at least between a first position and a second position. |
