  • Patent number: 11225884
    Abstract: A rocker arm has two side walls and two webs which run transversely with respect to the side wall. The webs connect the side walls to one another on end-side sections, wherein a valve stem support is configured on one of the webs, and a spherical cap is configured on the other web. A cam roller is arranged in a roller pocket which is delimited by the webs and the side walls. The cam roller is mounted rotatably on a roller axle which is fixed in the side walls. Projections are arranged within the roller pocket such that they are spaced apart from the respective web to guide the cam roller. The projections extend from the side walls in the direction of the cam roller to form guide surfaces which interact with end surfaces of the cam roller.

  • Patent number: 9556755
    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).
