Abstract
A switchable finger lever () for a valve drive of an internal combustion engine is provided. The inner lever () of the finger lever includes a piston () on one end thereof, that can be longitudinally displaced, and acts as a coupling element. The coupling element can be partially brought into contact with a driving surface () of an outer lever (), and is provided, for example, with a rising radial profile () in the coupling region thereof, and from the front () in the coupling direction. The driving surface () of the outer lever () also has a conical contour which follows the profile (). During coupling, a contact point (K) of the piston () is located on the driving surface () in a region of half a depth thereof. In this way, the formation of undesired edge supports is prevented during coupling.
