LOW MASS DIRECT ACTING HYDRAULIC VALVE LIFTER A direct acting hydraulic valve lifter features in a preferred embodiment a follower assembled with a thin wall metal shell and a light plastic baffle to support a lash adjusting hydraulic element assembly. An inlet riser chamber has sufficient cross section to minimize oil flow restriction in cold oil conditions. Dead space between the shell and baffle is filled with a strong lightweight foam to support and retain the baffle and displace oil for low mass.
