The cam followers drive the tappets by means of the contact surface with the roller thereof. The guide systems are embodied with slide blocks (11), adjustable within slide housings (10), guide arms mounted in rollers and guide levers mounted in crank levers. According to application, the guide systems comprise contact surfaces, rollers or pivot joints.
