Switchable valve lifter

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 3>hybridized carbon.
