Abstract
A camshaft adjuster has a stator, a rotor rotatable relative to the stator with a hub for receiving a camshaft. First supply ducts and second supply ducts penetrate the hub radially, and a separating sleeve inserted with an end section into the hub and forms an outer axial supply space and an inner supply space which is separate from the former, wherein the outer axial supply space is connected in flow terms to the first supply ducts and the inner axial supply space is connected in flow terms to the second supply ducts. On the outer shell, the separating sleeve includes a number of axial grooves at least partially forming the outer axial supply space connected to the first supply ducts. The separating sleeve includes a number of radial apertures which connect the inner supply space to a second supply line.
