Beschreibung
Zusammenfassung:	The present invention provides for Variable Valve Actuation comprising a cam, a valve suitable to displace between a closed position and an open condition caused by said cam, and further comprising a main rocker arm suitable to swing over a fulcrum, mechanically interacting with said valve, by means of a guide profile, and wherein said cam interacts with said main rocker arm causing said valve displacement as a consequence of said main rocker arm swinging. The target is to prevent a valve brake due to the guide profile and enable higher system stiffness. Accumulator less designs are feasible with this system.
