Abstract:
1. A finger lever of a valve train of an internal combustion engine, said finger lever being switchable to different lifts for at least one gas exchange valve and comprising an outer lever and an inner lever arranged between arms of the outer lever, said outer and inner levers being capable of pivoting relative to each other and of being coupled to each other by a coupling element, so that, in a coupled state, a high valve lift and in an uncoupled state, a low or zero valve lift is generated, a support for a gas exchange valve being arranged on one end of an underside of the finger lever, and a complementary surface for a support element being arranged on a further end of the underside of the finger lever, an upper side of the outer lever comprising at least one running contact surface for a high lift cam and an upper side of the inner lever comprising a running contact surface for a low or zero lift cam, wherein the arms of the outer lever are connected in a region of the further end by a crossbar, a slide constituting the coupling element being arranged for sliding in a longitudinal bore extending within the inner lever above the complementary surface or in a region of the complementary surface, for coupling the inner and outer levers, the slide can be displaced toward the further end partially out of the longitudinal bore so as to engage an entraining surface configured as one of an underside of the crossbar or a bore of the crossbar, and, in a region of the one end, the inner lever is pivotally connected to the arms of the outer lever.
