A hydraulic camshaft adjuster of the vane cell type, including a rotor and a stator and including a cover having fastening holes extending all the way through for accommodating fasteners. Via the fasteners the cover is fastened at an end face to the stator. The cover has a locking hole, into which a locking pin accommodated in the rotor can be displaced in an axial direction in order to lock the rotor in relation to the stator. The position of the locking pin in the rotor is pivoted about the axis of rotation by an angle in relation to a fastener when the camshaft adjuster is used as an exhaust adjuster, the position of the locking pin in the rotor is pivoted about the axis of rotation by an angle α″ in relation to a fastener when the camshaft adjuster is used as an intake adjuster, and the position of the locking hole in the cover is pivoted about the axis of rotation by an angle α in relation to the position of a fastening hole, wherein the rotor and the stator are coordinated with each other in such a way that the angles α, α′, and α″ are equal in magnitude and the pivoting directions of the angle α′ and α″ are oppositely directed.
