Valve drive component (sic) for transfer of stroke by cam projections on gas change valve, internal combustion engines has protection layer of at least one metal-free amorphous hydrocarbon layer with sp2 and sp3 carbon

摘要

Switchable valve drive component (sic) for variable transfer of a stroke produced by cam projections on a gas change valve of an internal combustion engine with transfer members which can be combined (verbindbar) and form-closed (sic) in the transfer direction via coupling elements. Force transfer surface section (16) of coupling element can be inserted between force transfer surface sections of a transfer element. The force transfer surface sections have a wear protection layer (23) consisting of at least one metal-free amorphous hydrocarbon layer with sp 2- and sp 3hybridized carbon.
