Control time altering device has sheet component with friction-enhancing coating between camshaft-facing endface of driven unit and endface of camshaft

摘要

The control time altering device has a sheet component (20) with a friction-enhancing coating (19) between the camshaft-facing side surface (16) of the driven unit (9) and the endface (15) of the camshaft (3). This enables the necessary pre-tension of the central fixing screw (13) to be reduced and more easily checked.
