摘要：The invention proposes a coupling mechanism () for relatively movableelements () of a switchable cam follower () of a valve train of an internal combustionengine, a high lift being obtainable upon coupling of said elements () and a lift smallerthan the high lift being obtainable upon uncoupling of said elements (), a first one () of
said elements comprising a guide bore () for at least one coupling piston () which, forachieving coupling, can be displaced partly beyond a parting surface () between saidelements () into an aligned reception () of a second one () of said elements, wherein uponcam lift and coupling of said elements (), a contact zone () between the piston () and thereception () is clearly spaced from an edge section () of the reception () on the partingsurface (). This can be implemented in practice, for instance, through a special“backwards” oriented flattened portion () on the piston (). Material loading on theedge section () is thus avoided.
