Internal combustion engine valve actuation control arrangement

An internal combustion engine valve actuation control arrangement having a hollow camshaft (31) with at least three independently axially displaceable cam elements (10, 11, 12), and a switch gate (13) disposed between a first and a second of the at least three independently axially displaceable cam elements (10, 11) with axially adjacent gate sections having at least one continuous gate track (14, 15) provided for sequentially displacing the at least three independently axially displaceable cam elements (10, 11, 12) one after the other, the switch gate (13) comprising three switch gate segments each associated with one of the at least three independently axially displaceable cam elements (10, 11, 12), the first and second independently axially displaceable cam elements (10, 11) being connected directly to, or part of, the adjacent switch gate segments and the third independently axially displaceable cam element being connected to a third switch gate section (22) by way of a connecting unit (23) extending through the hollow camshaft (31), the at least one continuous gate track (14, 15) extending in the at least three switch gate segments (16, 17, 18, 19, 20, 21), each of which is associated with one of the at least three independently axially displaceable cam elements (10, 11, 12).
