Patent ID: 7493878

Claim:
A device for variable actuation of gas exchange valves of an internal combustion engine having rotational speed, comprising: a camshaft with at least one cam mounted in a housing and rotating independently of said rotational speed of said engine; an intermediate link driven initially by said cam and carrying out an oscillating rotational movement about an axis of rotation in said housing; an adjusting cam having a control cam with a pause region and a lifting region, said axis of rotation being shiftable parallel to itself along said adjusting cam; a power take-off element actuated by said control cam and actuating at least one of said gas-exchange valves; said intermediate link being mounted on a bolt with an axis corresponding to said axis of rotation of said intermediate link, said bolt being mounted parallel displaceably on said adjusting cam with parallel displacement; cam discs and tappets supported against said housing and producing said parallel displacement; an adjusting shaft mounting rotatably with said cam discs at said housing, said cam discs producing an adjusting movement transferred over said tappets onto said bolt.
