Abstract (en)
The invention describes a system for continuously varying the lift and the phase of the valves in an internal combustion engine of the type comprising at least one camshaft (22) provided with at least one pair of cams (26), at least one intake valve (10) and at least one discharge valve (12) each commanded by a rocker arm (14) provided with a roller (16). Each rocker arm (14) is commanded by the respective cam (26) of the camshaft (22) through the interposition of at least one intermediate rocker arm (24). In this way, the system is able to simultaneously and completely mechanically vary both the lift and the phase of the valves of an internal combustion engine.
