The valve train assembly with magnet uses the magnet to collect ferrous metal particles that are in the oil prior to their arrival at the high pressure cavity of the hydraulic lash adjuster. The magnet can be positioned in the low pressure cavity of the hydraulic lash adjuster, in the bore of the hollow rocker arm shaft or in the bore of the hollow push rod.

A switchable valve-drive component () for variable transmission of a stroke generated by one or more cam projections to a gas-exchange valve of an internal combustion engine is provided. The valve-drive component () has transmission elements (), which can be connected with a positive fit by coupling elements () in the transmission direction, in which force transmission surface sections () of the coupling elements () can be clamped between force transmission surface sections () of the transmission elements (). Here, at least one of the force transmission surface sections () should be provided with a wear protection layer (). This layer comprises at least one metal-free amorphous hydrocarbon layer with sp-hybridized and sp-hybridized carbon.
