Abstract
An angular adjustment is provided between a crankshaft and camshaft by a hydraulically operated rotary vane, which is pivotably mounted on the camshaft and is supported on a sprocket wheel carrier driven by a crankshaft rotation of the vane causing a relative rotation to take place between the crankshaft and camshaft. The rotary vane is held in each of its two end positions by a spring device.
