Abstract

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.
