Abstract | In an internal combustion engine with variable actuation valves, each variable actuation valve is actuated by an actuator assembly including an actuating piston (21) slidably mounted in a guide bushing (22). Between the actuating piston (21) and the stem of the respective valve is interposed an auxiliary hydraulic tappet (400) positioned outside the guide bushing (22) of the actuating piston (21), so that said bushing can be dimensioned with a relatively small diameter, regardless of the outer diameter of the auxiliary hydraulic tappet (400). The intake valves of a same cylinder are actuated by a single cam, by means of a single pumping piston (16) and by means of a single pressure chamber controlled by a single solenoid valve (24). |
