A variable stroke valve drive for an internal combustion engine, including an intermediate lever which is slidingly arranged on a crank path of a crank arm the intermediate lever has a working cam with null lifting cam and lifting cam portions. The working cam contacts a gas exchange valve via an intermediate element. A first adjustment element rotates the intermediate lever against a spring element around a point located near the crank, the intermediate lever being displaceable along the crank path by a second adjustment element. The first adjustment element is provided with a cam plate whose radius continuously increases or reduces on a circumference with respect to an axis of rotation. The inventive variable stroke valve drive substantially reduces wear in a valve drive.
