Variable stroke valve drive for cylinder head of internal combustion engine, has pivot lever, which has cam track on side facing cam, where intermediate element is arranged between cam and cam track and is displaced along cam track

摘要

The variable stroke valve drive (1) has a pivot lever (2), which is pivotally supported on one side and is supported on an intermediate element (8) on a gas exchange valve (9) in a backlash-free manner. The pivot lever has a cam track (15) on the side facing the cam (10). An intermediate element (16) is arranged between the cam and the cam track and is displaced along the cam track. The intermediate element is a roller, whose position is changed by a gear (17). An independent claim is included for an internal combustion engine with a pressure gas reservoir.
