Abstract

In a valve train of an internal combustion engine having a switchable support element (1), the lost motion spring (18) of the support element (1) is arranged axially offset next to the support element (1) while being coupled to an inner element (3) of the support element (1) by a crossbar (20). Due to this externally positioned spring (18), the support element (1) requires only a relatively small design space.
