Abstract

A valve train comprises a double camshaft with an inner camshaft and an outer camshaft. The two camshafts are preferably designed coaxially. By means of a rotatory change in position of the inner camshaft to the outer camshaft, the angular position of at least one cam of the inner camshaft is adjusted or set relative to a cam of the outer camshaft. The cams are divided into sets that can occupy variable cam positions relative to one another. Various configurations of a camshaft adjuster are provided for this purpose.
