Abstract: The invention concerns a drive for valve drive operating control systems in motor vehicles, preferably for camshaft adjusters, comprising at least one drive wheel (2) and functional parts, such as a cover (3), a stator (6), a closing ring (4), and a sealing ring (28), as well as at least one rotor (7). It is suggested that the drive wheel (2) and at least one of the functional parts (3 through 6) are produced in a single part from a high-resistant, non-metallic material.

Abstract: A camshaft adjuster for motor vehicles has a stator and a rotor rotatable relative thereto between which pressure chambers are provided. Pressure medium is supplied in a controlled way via a valve to the pressure chambers in order to rotate the rotor relative to the stator. Mounting of the valve in the internal combustion engine of the motor vehicle is often difficult when mounting conditions are tight, sometimes even impossible. In order for the camshaft adjuster to be usable even in tight spatial conditions, the valve is arranged on the side facing away from the camshaft connection. The valve can therefore be arranged stationarily axially outside of the engine of the motor vehicle. The camshaft adjuster requires thus only little mounting space.

Abstract: At least one locking device between an interior part and cellular wheel, which is equipped with a movable locking element that acts together with at least one counter-element in a respectively other component of the two components cellular wheel or interior part, causes the interior part to be able to be locked relative to the cellular wheel in at least one final position. The locking and/or unlocking process of the locking element occurs through at least one oil duct that leads to the locking element. Between two pressure chambers in or on the cellular wheel an opening connected with the oil duct is arranged, whose passage to the two pressure chambers is controlled in dependence on the adjusting position of the interior part. This way, the cam shaft adjusting unit can be locked safely.
