Abstract: An engine valve actuation mechanism for producing a variable engine valve event includes a cam, a rocker arm, a rocker arm shaft, an eccentric rocker arm bushing, and a bushing actuation device. The eccentric rocker arm bushing is disposed in an axial hole in the rocker arm, the rocker arm shaft being disposed in the eccentric rocker arm bushing with the rocker arm shaft and the eccentric rocker arm bushing having offset axial centerlines. One end of the rocker arm and the cam is connected to form a kinematic pair and the other end of the rocker arm is located above the engine valve with a gap between the cam and the engine valve. The bushing actuation device is placed in the rocker arm and drives the eccentric rocker arm bushing to rotate, and the rotation of the eccentric rocker arm bushing changes the gap to generate the variable engine valve event.

Abstract: A cam follower for a valve train of an internal combustion engine, the cam follower being formed as a lever, which is U-shaped in cross-section, and produced from steel sheet without machining, and which has a floor wall (3) and lateral walls (4 and 5) extending therefrom, wherein a valve stem support (10) is disposed as a groove (11) at one end of the lever in a surface of the floor wall (3) facing away from the lateral walls (4 and 5). Lateral guide walls (12 and 13) of the valve stem support (10) are formed by chipless shaping so as to extend from and counter to the lateral walls (4 and 5) and are connected to a support wall (14) that forms a valve stem support surface (10a). The valve stem support surface (10a) extends in a first plane (10b), which is spaced from a second plane (16a), which extends through an internal transition (15, 16) between the lateral walls (4 and 5) and the adjacent guide walls (12 and 13), in the direction of ends (19, 20) of the lateral walls (4 and 5). In order to reduce stress and resulting cracks, an inner radius R is provided at the transition (15 and 16), by which radius a free space (17, 18) is created between the lateral wall (4, 5) and the guide wall (12, 13), which free space narrows towards the end (19, 20) of the respective lateral wall (4, 5).
