ABSTRACT:
Camshaft adjusters which work in accordance with the operating principle of a hydraulic oscillating motor comprise at least two components arranged parallel to one another. Frequently, the two components are a covering plate and a stator. The two components are connected by fasteners which penetrate through one of the two components. At least one of the fasteners is equipped with a central, deformable pin which, in the obstructed state, impedes the nondestructive separation of the two components arranged parallel to one another.
