ABSTRACT:
A valve lift mechanism, in particular for internal combustion engines of motor vehicles, has a driven cam element, a valve control member which can be driven (translational movement or pivot rotation) by the cam element, and a flexible enveloping element, wherein the cam element is rotationally mounted. The enveloping element may be formed of an open loop with two ends connected by a holder of said valve actuator, and it is movably connected to the valve control member in the plane perpendicular to the axis of rotation of the cam element.
