Abstract: A phase shift mechanism including a plate carrying a pair of oppositely disposed idler sprockets, the plate being pivotally mounted on the crankshaft of an internal combustion engine so that the idler sprockets engage the timing chain at opposite points of its internal periphery and may adjustably control the position of the chain relative to the camshaft and crankshaft by the pivotal movement of the plate on the crankshaft thus effecting phase shifting between the two shafts and changing valve timing relative to piston position.
