Abstract

An angle of rotation of a camshaft relative to an angle of rotation of a crankshaft in internal combustion engines is adjusted for influencing the control times of a valve operation sequence. A wobble plate mechanism including a wobble drive realizes the adjustment. The wobble plate mechanism is arranged between camshaft and crankshaft, preferably between camshaft and a camshaft wheel.
