Abstract
In a switchable support element (1) for a valve train of an internal combustion engine, the lost motion spring (8) of the valve train is made as a torsion spring. This spring is arranged outside of the support element (1) and only the legs and the arms of the spring engage a housing and a head, respectively. In this way, the support element (1) requires no substantially larger design space than non-switchable prior art elements, particularly in axial direction.
Claims21
A switchable support element for a finger lever of a valve train of an internal combustion engine, said support element comprising a housing, an inner element, a coupling means and at least one spring, the housing being telescoped with the inner element which is biased away from the housing by the spring and extends beyond an end the housing by a head that comprises a support for the finger lever, the coupling means being configured for selectively coupling the housing to the inner element in an axially extended state of the housing and the inner element, wherein
- the spring is arranged substantially or entirely axially outside of the housing while being supported with one end in a region of the end of the housing and with a further end, on the head of the inner element in a vicinity of the support of the head,
