Abstract
A camshaft adjuster for a concentric camshaft assembly of an internal combustion engine is provided. The adjuster includes a stator that is connected to the timing gear, and a rotor located within the stator having a plurality of vanes that extend into spaces created between inwardly directed projections of the stator to define chambers on each side of the vanes. Front and rear sidewalls are connected to the stator and form the front and rear walls of the chambers. An outer cover connects to the stator to the inner camshaft via a drive adapter, and the rotor is connected to the outer camshaft. Radial loads acting on the timing gear are transmitted from the stator to the rotor and into the outer camshaft. The drive adapter includes an open cylindrical body having first and second ends. The first end includes a slot or recesses in which a timing feature of the cover engages. The second end has a keyed portion configured to matingly engage a corresponding portion of the inner camshaft.
