ABSTRACT:
In an apparatus for valve actuation in a multi-cylinder internal combustion engine, a valve is actuated by two actuation levers which can be coupled together by coupling elements. The actuation levers are driven by two cams with different cam protrusions. In order to avoid wear-causing incomplete coupling for all the coupling elements when the cam protrusions become effective, their triggering for coupling and decoupling only takes place within an interval of time fixed with respect to the camshaft position. When the cam protrusions become effective, the coupling or decoupling procedure is either concluded or at least a sufficient overlap of the coupling elements is produced.
