Abstract:
Proposed is a switchable valvetrain (1) for an internal combustion engine, having a row of rocker arms (2) which extend in the longitudinal direction of a cylinder head, which rocker arms (2) run via a recess (7) on an upper side (6) on a head (8) of a bearing journal (9), which bearing journal (9) is axially moveably arranged in a bore (10) of a carrier (11) which runs above, with piston-like coupling means (12) being provided for selectively coupling the bearing journal (9) to the carrier (11).
