Abstract
A camshaft unit includes a camshaft having a radial channel, a hydraulic phase setting device communicating with the radial channel for adjusting the phase length of the camshaft with respect to a crankshaft via hydraulic pressure medium and a pressure medium channel embodied as a solid cylinder head component. To transfer a pressure medium, at least one pressure medium transfer element is formed between the pressure medium channel and the radial channel. The pressure medium transfer element includes a ring channel including a ring channel opening extending in the peripheral direction of the ring channel and including a radial channel opening leading into a radial channel and opposite the ring channel opening. The pressure medium channel communicates with the radial channel via the ring channel opening and the radial channel opening.
