摘要： A switchable finger follower for a valve train of an internal combustion engine includes an outer and an inner lever, which at a first longitudinal end run pivotably relative to one another via respective bores on a common shaft. At this longitudinal end, the finger follower has a gas-exchange valve contact face on an underside. The outer lever has a pivot bearing on the underside at a further longitudinal end, and at least the inner lever has a cam running face on an upper side. The inner and outer levers are connectable to one another via at least one coupling slide, which spans a separation area between the levers. The outer and inner levers are braced relative to one another via a cam return spring, and the shaft is connected to the bore of the outer lever by an interference fit. To mount the inner lever relative to the shaft without radial play but in a rotatable fashion, the bore of the inner lever includes, in its semi-circular segment facing the upper side, a pointed arch composed of two circular arcs as contact means.

摘要： The invention relates to a locking device for a switchable valve drive component, including a first locking body and a second locking body which can be brought into engagement with one another or out of engagement in order to couple to one another or to uncouple two component parts arranged movably with respect to one another, wherein at least one of the two locking bodies has at least one curved surface. In order to increase the wear resistance of the locking device, provision is made for at least one of the two locking bodies to have a plurality of curved surfaces of which the respective curvature is described by radii of identical length having constructional center points spaced apart from one another.
