Switchable finger lever of a valve train of an internal combustion engine

A switchable finger lever of a valve train of an internal combustion engine, said finger lever comprising an outer lever between whose arms an inner lever extends for pivoting relative to said arms, at least said inner lever possessing on an upper side, a cam contacting surface, a support for at least one gas exchange valve being arranged on an undersurface on one end of the finger lever, said inner and outer levers extending on a common axle in a region of said one end, said finger lever further comprising a lost motion spring means acting between said inner and outer levers, said outer lever possessing on the undersurface on another end, a contact surface for a support element, a longitudinally displaceable coupling element being arranged above or laterally of said contact surface, which coupling element, for realizing coupling, can be brought partially into engagement with an entraining surface of an adjoining crossbar of the inner lever, wherein the inner lever, starting from said crossbar on the another end, merges into a box-like open center portion having two bar-shaped arms that, in a direction toward the one end, comprise crossbar sections that are strongly bent toward each other and extend further in form of a common, thin-walled bar comprising an eye that surrounds the axle in a central region of the axle, the outer lever comprises a box-like open center portion comprising said arms of the outer lever between which the center portion of the inner lever extends and that are likewise bar-shaped, these bar-shaped arms of the outer lever extend further in direction of the one end in form of transversal sections that are strongly bent toward each other and end in two parallel fingers while being arranged through bores on the axle, and the outer lever, at least starting from said arms in the center portion of the outer lever up to the fingers on the one end, adjoins the inner lever in a wall-against-wall engagement, the arms of the outer lever taper in direction of the another end to end in a solid end piece comprising the coupling element, said end piece being made as one of an integral part of the arms or a separate insert element, the bar of the inner lever on the one end continues beyond the axle into a lug-like extension that serves as a one-end support surface for the lost motion spring means.
