Radial camshaft pressure medium transfer

A camshaft assembly comprises:

• a camshaft having at least one radial channel;
• a hydraulic phase setting device communicating with the at least one radial channel and for adjusting a phase angle of the camshaft with respect to a crankshaft with the aid of a hydraulic pressure medium;
• and
• a pressure medium channel provided in a cylinder head-affixed component;
• at least one pressure medium transfer element formed between the pressure medium channel and the at least one radial channel of the camshaft;
• the at least one pressure medium transfer element including at least one annular channel having an annular channel opening extending in a circumferential direction of the annular channel, and at least one radial channel opening opposite the annular channel opening and emptying into a further radial channel;
• the pressure medium channel communicating with the at least one radial channel of the camshaft via the annular channel opening and the at least one radial channel opening of the at least one annular channel of the at least one pressure medium transfer element.
