A camshaft adjuster which has an improved configuration of the pressure chambers and of the adjoining pressure chamber surfaces is provided, that is attached at the end side to a camshaft (2), coaxially about a camshaft axis (3), and which acts as a transmission element to a drive wheel (4) for rotationally driving the camshaft (2), having an inner wheel (5) which is arranged so as to be rotationally fixed with respect to the camshaft (2) and having an outer wheel (6) which is arranged so as to be rotatable, and coaxial, with respect to the inner wheel (5). At least one inner wheel vane (7) is arranged on the inner wheel (5) and at least one outer wheel vane (8) is arranged on the outer wheel (6), between which inner wheel vane(s) (7) and outer wheel vane(s) (8) are formed pressure chambers (9, 9a). The inner wheel vanes (7) delimit the pressure chambers (9, 9a) with a lateral pressure chamber surface (10), and radial bores (11) are formed in the inner wheel vane (7) for a pressure medium supply to the pressure chambers (9, 9a). The inner wheel vanes (7) have, within the pressure chamber surface (10), at least one recess (12) into which the respective radial bores (11) open. |
