Patent abstract
The mechanical variable cam timing device has a camshaft connector, a sprocket, a sprocket ring and a connector ring, all of which have teeth with slanted side walls that mate to form a circumferential ring. The sprocket ring and the connector ring move axially so as to shift the spacing between the teeth and provide for a phase shift.
