Abstract
An adjusting shaft actuating device of a valve train for internal combustion engines includes a cam unit with first and second cams rigidly connected thereto. The second cam is spaced apart from the first cam in axial and peripheral directions. The device also includes a lever unit non-rotatably arranged on an adjusting shaft with first and second lever arms rigidly connected thereto. The second lever arm is spaced apart from the first lever arm in axial and peripheral directions. The first and second cams are configured to be brought into respective operative connections with the first and second lever arms by an axial alignment between the cam unit and lever unit. The first and second cams and the first and second lever arms are arranged such that the first operative connection and the second operative connection are produced during a rotation of the adjusting shaft in a temporally consecutive manner.
