Abstract
What is proposed is a switchable tappet ( ) for the direct transmission of a cam lift to a tappet push rod. The tappet ( ) comprises a hydraulic clearance compensation element ( ) and has an excellent hydraulic rigidity compared to the prior art. This is achieved by a leak gap positioned radially very far outwards. This leak gap is situated directly between a housing ( ) and a pressure piston ( ) which, in its turn, encloses an inner element ( ) that acts on a tappet push rod.
