Patent ID: 7293538

Claim:
A camshaft drive for an internal combustion engine, the drive comprising: a drive sprocket connectable with a crankshaft rotatable on a first axis; a driven sprocket connectable with a camshaft rotatable on a second axis spaced from the first axis; an input sprocket and an output sprocket rotatable on a third common axis, spaced from the first and second axes, and connected with a cam phaser operable to vary the phase angle between the input and output sprockets; and a first chain connecting the drive sprocket with the input sprocket and a second chain connecting the output sprocket with the driven sprocket whereby the cam phaser is operable to vary the phase angle between the drive and the driven sprockets; wherein the cam phaser is carried on a stationary hub extending from a mounting member fixed on an offset face of an engine block so that the extension of the drive and the driven sprockets from the front of the engine can be minimized.
