The invention relates to a valve train mechanism (10) comprising at least one camshaft (11), having a first valve actuating unit (18) for actuating at least one first gas exchange valve (38, 59), which is provided to convert a rotary motion of the camshaft (11) into a force for switching between two different cam followers (40, 41) associated with the at least one first gas exchange valve (38, 39), and having a second valve actuating unit (19) for actuating at least one second gas exchange valve, which is provided to convert a rotary motion of the camshaft (11) into a force for switching between two different cam followers associated with the at least one second gas exchange valve, wherein the first valve actuating unit (18) has at least one first release element (21, 22) connected to the camshaft (11) for conjoint rotation, and the second valve actuating unit (19) has at least one second release element (23, 24) connected to the camshaft (11) for conjoint rotation, wherein the release elements (21, 22, 23, 24) are coupled to each other, and an internal combustion engine comprising a valve train mechanism (10) according to the invention and a method for operating a valve train mechanism (10) according to the invention, in which the release elements (21, 22, 23, 24) are actuated simultaneously and the release elements (21, 22, 23, 24) trigger successive switching of the associated valve actuating units (18, 19) between the cam followers (40, 41). |
