Abstract:
According to the present invention, an outer lever (1) of a finger lever (2) that can be switched to different lifts for at least one gas exchange valve is made by a deep drawing method. A salient feature of the invention is that a cup-shaped base body (16) having an inverse U-shaped cross-section is deep drawn, and opposing running contact surfaces (14, 15) for high-lift cams are created on arms (4, 5) of the outer lever (1) by punching out a bottom (19) of the base body (16). Through the deep drawing method of the invention, only relatively low fabrication costs are to be expected.
