  • Patent number: 11933199
    Abstract: 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.
