DEVICE FOR THE VARIABLE ACTUATION OF THE GAS EXCHANGE VALVES OF INTERNAL COMBUSTION ENGINES

摘要

The valve operating device has a camshaft (1) rotated in dependence on the engine revs, fitted with cams (2), used for operation of respective gas changing valves (13) via intermediate cam elements (4) and valve drive elements (11). The intermediate cam elements are fitted to a bolt (6), defining the rotation axis (7) for the intermediate cam elements, which can be displaced parallel to a setting curve (8) under control of a setting shaft.
