  • Patent number: 8850925
    Abstract: A follower member (1) for a valve train of an internal combustion engine, the follower member (1) having a roller (3) mounted on a pin (2) for a running contact against a periodic stroke producer, the roller (3) being mounted with an inner peripheral surface (4) on an intermediate ring (5) extending directly on the pin (2) and forming, together with said the (2), an intermediate sliding bearing (6) situated between the intermediate ring (5) and the pin (2), and the intermediate ring (5) protruding beyond two front ends (7) of the roller (3). The intermediate ring (5) has a clearly higher surface hardness than the pin (2).

  • Patent number: 8733310
    Abstract: A finger follower lever for actuating gas exchange valves of an internal combustion engine, having a lever body formed by two parallel side walls spaced apart by a transversely extending web. The web forms a first, joint socket end as a pivotable support for the lever, and a second end with a valve actuating surface. A cam roller is rotatably held between the side walls via a needle ring of a needle bearing. The cam roller projects partially via an aperture in the web for cam contact. The cam roller is narrow, and the needle ring projects beyond the cam roller at one axial end, and ends directly adjacent to a corresponding side wall. The aperture has a cross section defined by an overlap between a first, cam roller pocket with an extent corresponding to the cam roller in the axial direction, and a second pocket for the needle ring.
