Abstract
A camshaft adjuster () having a variable ratio gear unit (). Usually, a drive movement of an electrical actuating assembly () is transmitted into a variable ratio gear unit () of a camshaft adjuster () on the side which faces away from the camshaft (). According to the invention, the abovementioned drive movement is transmitted in from the side of the variable ratio gear unit () which faces the camshaft (). As a result, a further assembly, for example a vacuum pump, can be driven by the variable ratio gear unit () on the side of the variable ratio gear unit () which has become free and faces away from the camshaft (). An actuating shaft () of the actuating assembly () is preferably mounted via a bearing () which is supported on a circumferential face of the camshaft (). This results in a reduced axial overall size of the camshaft adjuster and extended possibilities for the arrangement of an actuating assembly and the connection of additional assemblies.
