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.
Claims7
A valve train of an internal combustion engine, said valve train comprising one or more switchable support elements that are arranged with an inner element for a relative axial displacement in a reception of a cylinder head of the internal combustion engine, which inner element extends beyond the reception by a head comprising a support for a finger lever, a coupling means for a selective coupling of the inner element relative to the reception in an axially extended state of the inner element out of the reception being associated to the support element, while the inner element is biased away from the reception by at least one spring, wherein
- the spring is arranged axially offset next to the support element and is coupled to the inner element by a crossbar and the spring is configured as at least one mechanical spring element in form of a coil or flat coil spring and extends on or at least partly in the cylinder head, a guide column being provided as a linear guide for the crossbar parallel to a longitudinal axis of the support element.
