Abstract
The invention provides a valve train for an internal combustion engine, comprising an elongate anti-rotation bridge () acting as a retention device and a mounting aid and comprising receptions () for valve lash adjusters arranged spaced behind one another. A valve adjuster configured as a roller tappet () is arranged in each reception () while being directed through a tappet roller () toward a cam of a camshaft. The roller tappet () is retained for longitudinal displacement in the reception () and is secured against rotation through flat key surfaces arranged on its outer peripheral surface that bear against corresponding inner surfaces of the anti-rotation bridge (). An opening () of the anti-rotation bridge () for allowing a passage of a tappet pushrod that is supported on an end of the roller tappet () is associated to each reception (), and a support surface () limiting each reception () is configured in the anti-rotation bridge () for supporting that end of each roller tappet () that faces away from the tappet roller.
