Side load free egr valve actuation

Abstract

The invention relates to a device for converting a rotational motion of a valve element into a translational motion of same with: a valve element bearing-supported such that it is translationally movable along a translation axis, a cam element with a cam curvature, wherein the cam element is rotatable about an axis of rotation, wherein connected with the valve element is a stem by means of which the valve element can be moved translationally along the translation axis and which comprises an engagement element in engagement with the cam curvature, wherein the engagement element is braced from two sides of the cam element by the stem, and wherein, by rotation of the cam element about the axis of rotation, the engagement element is guided along the cam curvature such that the stem executes a translational motion whereby the valve element executes a translational motion.
