Valve drive for internal-combustion engine, has supporting element arranged non-contactly to axial projection in position overlapping in circumferential direction, where supporting element is placed against cam shaft in sections

摘要

The drive (1) has a cam shaft (2) provided on a rotatably-fixed and axially adjustable cam carrier (3). The carrier includes an axial projection (10) resting against the cam shaft on a side in sections. A supporting element (13) of a component (5) e.g. additional cam carrier, rotatably-fixed on the cam shaft and arranged non-contactly to the axial projection in a position overlapping in a circumferential direction. The supporting element is placed against the cam shaft in sections. A shifting device (15) includes an actuator inserted into a shifting slot (16) provided on the cam carrier.
