Apparatus for variable valve timing adjustment of an internal combustion engine

摘要

The device has a drive unit that stands in connection with a crankshaft, and a camshaft that stands in connection with an output unit (8). The drive unit is rotatably supported on the output unit/camshaft. A relative phase shift of the output unit relative to the drive unit is selectively varied or sustained by the adjusting mechanism. The drive unit is supported in an axial direction by radial and axial anti-friction bearings (19, 21).
