Abstract

A hydraulic, vane-type camshaft adjuster (1) having a rotor (2) and a stator (3) mounted such as to be rotatable relative to each other and to form vanes, wherein, for the radial positioning of the rotor (2) relative to the stator (3), a return spring (5) is or can be secured at one end to the rotor (2) and at the other end to the stator (3), and a spring contact component (15), especially in the shape of a ring, for centering the return spring (5) and/or limiting the radial position thereof, is fixed to the rotor (2) in at least two points.
