Device for controlling a valve of an internal combustion engine

摘要

A device connected to a valve stem for controlling a valve of an internal combustion engine. The device includes a cam having a first peripheral contour and a disk having a second peripheral contour smaller than the first peripheral contour. A first rocker arm is pivotable on an axle mounted bearing based on the second peripheral contour of the disk. A compensation device is positioned between the first rocker arm and the valve stem for maintaining contact therebetween. A second rocker arm is pivotable on the bearing based on the first peripheral contour of the cam. A drive selectively couples the second rocker arm to the valve stem. The drive includes a radially displaceable spherical driver disposed within the first rocker arm. A locking slide includes an engagement surface which radially displaces the spherical drive into a spherical depression on the second rocker arm so that the valve operates based on the first peripheral contour of the cam.
