Abstract

An apparatus for adjusting a camshaft of an internal combustion engine, having first and second shafts, of which the first shaft is driven to rotate at least indirectly by the engine and of which at least the second shaft is embodied as a camshaft for actuating a gas exchange valve of the engine, and the transmission of the rotary motion of the driven first shaft to the driven second shaft is effected by means of a coupling gear, by way of which moreover the relative rotary position of the shafts to one another can be varied. For the freest possible adjustment of the phase location of the shafts to one another, the coupling gear is embodied between the shafts as a planetary gear.
