Abstract
A switchable cam follower of a valve train of a combustion engine, which has an external lever that encompasses an internal lever between its arms. The levers are pivotally moveable relative to one another on an axis applied to a valve-side end. The cam follower also has a stop for a gas exchange valve on an underside on the valve-side end and on the other end has a complementary face for a support element. Additionally, the cam follower has a start face on an upper side for at least one high-lift cam. In one receptacle of one of the cams, a coupling element is seated, which can be brought into engagement in sections in case of coupling with a driving surface of the other lever. Further, a lost-motion spring is clamped between the two levers and is positioned in the region of the other end of the cam follower.
