Abstract

An apparatus for adjusting the motion characteristics of a valve of an engine, comprising an adjustment means to vary the valve opening and closing angle, or the valve lift including a guide element movable from a first position to a second position, and having a path adapted to receive a guide member of a valve actuation means, the guide member received in the guide path having a trajectory, when the adjustment means is in the first position, different of the trajectory of the guide member when the adjustment means is in the second position.
