Abstract
A camshaft assembly is disclosed which comprises an inner shaft (), an outer tube () surrounding and rotatable relative to the inner shaft (), and two groups of cam lobes mounted on the outer tube, the first group of cam lobes being fast in rotation with the outer tube, and each cam () lobe () of the second group being rotatably mounted on the outer surface of the tube () and connected for rotation with the inner shaft () by means of one or more drive members () passing through circumferentially elongated slots in the outer tube. In the invention, each drive member comprises a () drive component () engaged with fixed alignment in the cam lobe () and a separate fastener () that is rotatable to clamp the drive component against a flat surface on the inner shaft (), each drive member () being constructed such that during the tightening of the fastener () no relative () sliding movement is required at the interface between the drive component () and the inner shaft ().
