The frame point (7) of the drive rocker arm (5) and the frame point (8) of the driven rocker arm (6) of the double rocker arms (4-6) are positioned in a driven element (9) mounted so that it rocks on a frame point (12). The driven rocker arm (14) of a pre-positioned drive unit (14-16) touches the driven rocker arm (5).The driven element holding the frame points (7,8) is the driven element of an adjustment element (9-11) in the form of a quadrilateral. The drive gear is in the form of a drive element, coupling and driven element.
