Abstract
The invention proposes a connecting element () for retaining a lever-type cam follower (), that serves to activate a gas exchange valve () of an internal combustion engine, inseparably on a support element () comprising a spherical end () on which the cam follower () is pivotally mounted through a concave depression (). The connecting element () engages into an annular groove () under the spherical end (). In a connecting element () of this type, a central portion () of the connecting element () bears against an underside () of the cam follower () oriented toward the support element () and forms, through two legs () and a crossbar () connecting these legs () to each other, a U-shaped recess () in longitudinal direction of the cam follower (). This recess () engages around the groove () after the manner of a fork and orthogonally to a pivoting direction of the cam follower (), substantially without lash. Angled retaining claws () bent from the legs () extend in transverse direction of the cam follower () and engage after the manner of pincers over side walls () of the cam follower (). By a clamping of the retaining claws () through shaped sections () directed toward inner surfaces () of the side walls (), the U-shaped recess () is substantially fixed in respect of position in transverse direction of the cam follower () and in respect of shape.
