Abstract: In an adjustment device for a camshaft of an internal combustion engine for varying the phase relationship of a camshaft with respect to a crankshaft as a function of the operating point of the internal combustion engine, the adjustment device comprises an epicyclic gear structure with a drive-side and an output side ring wheel, which are in meshing engagement with planet wheels, and the output-side ring wheel has a number of teeth different from that of the drive-side ring wheel so that the position of the camshaft relative to the crankshaft can be adjusted via an electric servomotor which drives a central sun wheel.

Abstract: A control device for a cooling part-circuit and a heating part-circuit of an internal combustion engine. The cooling part-circuit includes a radiator and the heating part-circuit includes a heat exchanger. A delivery pump is connected to at least the cooling part-circuit and the heating part-circuit. The control device includes a rotary slide driven by a drive unit which is arranged in a valve housing. Provided in the valve housing are inlet or outlet openings for 1.) a cooling part-circuit which is connected to the radiator, 2.) a suction or pressure side of the delivery pump and 3.) at least two further part-circuits. The rotary slide is constructed as a substantially flat rotary disc with at least one control edge.
