ABSTRACT:
A camshaft drive system for an internal combustion engine includes a drive sprocket fixed upon a crankshaft of the engine and a driven sprocket fixed upon a camshaft of the engine. A flexible power transmission element extends between the drive sprocket and driven sprocket. A tensioning device for the flexible power transmission element includes a linear actuator and a number of movable contactors for engaging and tensioning both the slack side and the tight side of the power transmission element, such that proper phasing of the camshaft with respect to the crankshaft is maintained.
