Title: (EN) Rocker arm or finger lever formed by a chipless process
Abstract: front page image
(EN)

A rocker arm or finger lever (1) formed without machining (by a non-cutting shaping process) which has a U-shaped profile in cross section over almost its entire length which is open toward the top or the bottom, whereby the rocker arm or finger lever (1), in its end region in which it contacts a valve shaft end, is constructed double-walled. PAL This rocker arm or finger lever (1) is distinguished in that the double-walled section or at least a strap (13) projecting over the longitudinal extension of the rocker arm or finger lever (1) is formed on an upper wall (10) which is bent under and lies between its two side walls (11, 12). PAL A lever configured in this manner can be manufactured economically and has a good rigidity despite the reduced material used.
