A drive for valve drive operating control systems in motor vehicles, preferably for camshaft adjusters, includes at least one drive wheel and functional parts, such as a cover, a stator, a closing ring, and a sealing ring, as well as at least one rotor. The drive wheel and at least one of the functional parts are produced in a single part from a high-resistant, non-metallic material.

Drive for valve operating control systems in motor vehicles, preferably camshaft adjusters

A camshaft adjusting device for a motor vehicle has a stator and a rotor adjustable relative to the stator in a circumferential direction by a pressure medium. A restoring spring is arranged in a spring chamber and is configured to rotate the stator and the rotor relative to one another into an initial position when an engine of the motor vehicle is turned off. The restoring spring has a rotor end positive-lockingly connected to the rotor and a stator end positive-lockingly connected to the stator. One of the rotor end and the stator end is provided with a convexly curved embossment that cooperates with a convexly curved outer side of a positive-locking counter element on the rotor or stator, respectively. The embossment is provided at a radially outer end of the restoring spring. The restoring spring is a flat spiral spring.

Camshaft adjusting device for vehicles, especially motor vehicles

A camshaft adjuster for internal combustion engines of motor vehicles has a stator having a casing and stays connected to the casing and projecting radially inwardly. A rotor rotatable relative to the stator is fastened on the camshaft. The rotor has a rotor base member and vanes connected thereto. The vanes project into spaces between the stator stays. The stays each have an end face that rest sealingly against the rotor base member. The vanes of the rotor each have an end face resting sealingly against an inner peripheral wall of the stator. At least one of the vanes of the rotor has a damping element and the stator has at least one counter damping element. Upon rotation of the rotor into its end position, the damping element interacts with the counter damping element and slows the movement of the rotor into the end position.
