Abstract

A shaft device (2) drives a cam device (1) to activate a cam follower (3) that causes a coupling device (CD) (4) to activate a gas shuttle valve (5) in a variable manner adjusted in respect of coupling behavior. The CD has a primary adjusting drive (PT) for altering valve lift characteristics in a variable manner regarding valve lift as well as a secondary adjusting drive (ST).
