Mechanical valve tappet for an internal combustion engine

摘要

A mechanical valve tappet arranged in a guide bore of a cylinder head of an internal combustion engine, which valve tappet comprises a cup-shaped housing with a hollow cylindrical wall (1) closed at one end by a bottom (2) against which a control cam runs from the outside while an adjusting element (5) bears against the inner surface of the bottom by a first flat end face and is in contact with the end of a valve stem of a two-way gas valve by a second end face which is parallel to said first end face, characterized in that the adjusting element (5) is a solid component with a cylindrical outer peripheral surface and parallel end faces, projections being provided on the cup-shaped housing to cooperate with the cylindrical outer peripheral surface of the adjusting element so that the adjusting element (5) is retained by interlocking or by force engagement on the cup-shaped housing.
