Abstract
A valve-lift device for the variable control of gas-exchange valves of an internal combustion engine is provided. The device includes a pivotable lever that is capable of being driven by a camshaft, the pivotable lever having an axis of rotation which can be displaced in a slotted-link track fixed to the housing, and a valve actuation means. The pivotable lever has, at one end, a roller which is driven by a camshaft and, at its other end, a slotted-link roller which is moved along a working curve in a slotted link, the slotted link being designed as an engagement surface of a valve actuation means. A center of rotation of the lever is provided between the roller and the slotted-link roller and the center of rotation of the rocker lever and a supporting axis of the valve actuation means is arranged on a vertical axis in an operating position. In order to set a valve lift, an axis of rotation is displaced in a slotted-link track fixed to the housing.
