Provided is a camshaft phaser () having a driving member (), a driven member (), and a spring (). The spring () is axially preloaded in the spring cavity ().

Camshaft phaser having a spring

A camshaft adjuster () having a locking cover () formed of sheet metal, wherein the locking cover () has a substantially disc-shaped base surface () and has a collar (), which extends in an axial direction () and which runs at least partially around the base surface (), for receiving a spring cover (). As a result of the production of the locking cover () from sheet metal in combination with a turned-up collar (), the locking cover () can be produced simply and cost-effectively and nevertheless offers adequately high strength despite the low material thickness.

Camshaft adjuster

A hydraulic camshaft adjuster () having a rotor () and a stator () as well as a cover () which is situated in a rotatably fixed manner on the stator () and is separate from the stator (), having a spring () designed as a spiral spring (), the spiral spring () having an inner, first end () which is fixed on the rotor () in a form-locked manner and an outer, free end () which is fixed on the cover () in a form-locked manner, the second end () of the spiral spring () being located in a groove () present in the cover (), the groove () extending in such a way that the second end () of the spiral spring () extends from a side of the cover () facing away from the stator () to a side of the cover () facing the stator ().
