Abstract

A vane-type camshaft adjuster has a side plane that is arranged perpendicular to the center axis of the camshaft adjuster. A coil spring abuts the side plane and is connected between a rotor and stator to maintain the rotor at a certain angular position relative to the stator.In order to create a vane-type camshaft adjuster, the righting moments of which are adjusted in a particularly accurate manner, the coil spring has a rectangular profile, wherein a spring section is angled through the side plane such that the coil spring is supported relative to the stator or the rotor in a pivot-proof positive fitting manner.
