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.
Claims10
A vane-type camshaft adjuster having a stator and a rotor;
- said cam shaft adjuster defining central axis and having a side plane arranged perpendicular to the central axis a coil spring abutting said side plane and having a radial inner end and a radial outer end;
- said coil spring being connected at one of said radial outer and inner ends to said rotor and at the other of said radial outer and inner ends to said stator, whereby said coil spring strives to maintain said rotor at a certain angular position opposite said stator,
- said coil spring having a rectangular profile, wherein a spring section of said coil spring is angled through the side plane such that the coil spring is supported opposite the stator or the rotor in a pivot-proof positive fitting manner.
