Abstract
A switchable finger lever for a valve train of an internal combustion engine is provided, with the finger lever having an inner lever which cooperates at a valve-side end region with a gas exchange valve of the internal combustion engine and is connected at a support-side end region turned away from the valve-side end region pivotally to a support. Outer levers (1a, 1b) connected pivotally to the inner lever are arranged on both sides of the inner lever while being urged against the inner lever in a pivoting direction through a spring and being capable of being coupled to the inner lever through a coupling element. The outer levers (1a, 1b) are configured with an identical structure and each outer lever (1a, 1b) is configured symmetrically to the longitudinal lever axis (2).
Claims4
A switchable finger lever for a valve train of an internal combustion engine, said finger lever comprising an inner lever which cooperates at a valve-side end region with a gas exchange valve of the internal combustion engine and is connected at a support-side end region facing away from the valve-side end region pivotally to a support, outer levers connected pivotally to the inner lever are arranged on both sides of the inner lever and are biased against the inner lever in a pivoting direction by a spring and are adapted to be coupled to the inner lever by a coupling element, the outer levers are configured with an identical structure and each of the outer levers is configured symmetrically to a longitudinal lever axis, wherein each of the outer levers comprises on the valve-side end region, two parallel spaced-apart tabs configured symmetrically to the longitudinal lever axis, said tabs comprising aligned through-openings extending crosswise to the longitudinal lever axis, and the outer levers being pivotally connected to the inner lever through a cross-axle connection in the through-openings.
