Abstract
A camshaft adjuster has multiple locking guide slots and multiple locking pins spring-loaded in the direction of engagement with the locking guide slots and which, by varying assignment to the rotor and to the stator, are arranged relative to one another such that the rotor can, under the action of fluctuating torques, be automatically locked into the predetermined center position relative to the stator proceeding from a first early or late stop position by a successive engagement of the locking pins into the locking guide slots. The locking pins and the locking guide slots are arranged so that, in the event of a rotation of the rotor in the direction of the center locking position proceeding from the respective other second early or late stop position, the locking pins lock into the locking guide slots in the reverse sequence from different directions.
