Abstract

An intermediate lever arrangement for a mechanically-controllable valve drive arrangement, includes a pivot lever arrangement. At least one intermediate lever(s) comprising a working cam is configured to be in an operative connection with the pivot lever arrangement. A bearing shaft is arranged on the at least one intermediate lever(s). An engagement element comprising a circumferential point is mounted in the at least one intermediate lever(s) arrangement so as to rotate about an axis of rotation. A fixing device is arranged on the bearing shaft. The fixing device is configured to fix the engagement element in a defined position. A device is configured so that the circumferential point of the engagement element, upon a rotation by an angle α, describes a curved shape which deviates from an arc of a circle.
