摘要：
A tappet (1) is to be engageable on to at least three different cam profiles with an optional zero lift. To this end the tappet (1) consists of an annular base section (2) enclosing a circular base section (3). Both base sections (2, 3) can be coupled together via radially adjustable coupling devices (10). An additional, axially movable inner piston (18) is fitted in a guide sleeve (7) of the circular base section (3). The inner piston (18) can be decoupled via further coupling means (23) so that the tappet (1) can be completely decoupled from the guide sleeve (7).
