Variable valve train for an internal combustion engine

A variable lift valve train for an internal combustion engine with internal combustion, comprising a pivoted lever including a transmission surface on one end, a counter running surface in a central region and, on a further end, a support element and a contact element, said transmission surface comprising a zero lift path and, adjoining said zero lift path in a lever pivoting direction, a lift path, said transmission surface being in contact with a valve opener, said counter running surface being loaded by at least one lift cam, said support element being guided on a lever guide path, and said contact element, for adjusting a valve lift being loaded by an adjusting device in direction of said lever guide path, and the valve train includes an actuable element for creating an additional valve lift during a base circle phase of the lift cam that directly contacts the central region of the pivoted lever, wherein the cam base circle of the lift cam comprises at least one additional cam elevation as the actuable element for creating the additional valve lift, said zero lift path, as viewed from the lift path, being made up of a zero lift activating section, a zero lift shutting off section and a residual zero lift section and, for actuating the additional valve lift and creating a maximum valve lift, the pivoted lever is turned by the adjusting device only so far at a center of pivot of the adjusting device arranged on the further end that during the base circle phase of the lift cam the zero lift activating surface is in contact with the valve opener, and for deactivating the additional lift and realizing a high valve lift, the pivoted lever is turned by the adjusting device beyond the zero lift activating surface so far at a center of pivot of the adjusting device arranged on the further end that during the base circle phase of the lift cam, the zero lift shutting off surface is in contact with the valve opener.
