The invention relates to an internal-combustion engine with a hydraulic device
(1) for rotation angle adjustment of a camshaft (3) relative to a
crankshaft thereof, which is arranged on the drive-side end (2) of the camshaft
(3) supported in several radial bearings (4) in the cylinder head
(5) of the internal-combustion engine. The device essentially includes a
drive unit (6) drivingly connected with the crankshaft and also of a driven
unit (7) rotationally fixed to the camshaft (3). The drive unit (6)
is in force-transfer connection with the driven unit (7) through at least
two pressure chambers (12, 13), which are formed within the device (1)
and which can be charged with a pressurized medium, wherein the pressurized medium
is fed from one of the radial bearings (4) of the camshaft (3) and
supplied to the pressure chambers (12, 13) of the device via first and second
radial bore holes (14, 15) and via first and second axial channels (16,
17) in the camshaft (3), and also via first and second axial channels
(19, 20) and via first and second radial bore holes (21, 22) into
the driven unit (7). At least the first axial channels (16) formed
as coaxial bore holes in the camshaft (3) and the first axial channels (19)
in the driven unit (7) of the device (1) are connected to each other
via a ring-shaped pressurized medium adapter (23) arranged between the end
(18) of the camshaft (3) and the driven unit (7) of the device (1).
