Valve tappet system, especially anti-rotation bucket tappet having curved cam follower surface

摘要

A valve tappet system includes a base body, a lateral section, which forms a guide surface for guiding the base body along an oscillation axis. The anti-rotation element to suppress a rotational or swiveling movement about the oscillation axis. The anti-rotation element has a seat face which sits on the lateral section and a guide body which protrudes beyond the lateral section in the radial direction. Spaced first and second engagement protrusions are provided on the element, and the lateral section is provided with a first and second radial bores assigned to the respective first and second engagement protrusions, which are each engaged in the respective radial bore radially to the oscillation axis.
