Abstract (en)
[origin: EP1484479A2] A variable-lift timing system (10) for an internal combustion engine. The system (10) includes an actuating mechanism (12) for moving a valve (11). An intermediate assembly (15) is interposed between the valve (11) and the actuating mechanism (12), and includes a first contoured member (15a), a contoured surface (18) of which contacts the rod (11a) of the valve (11), and a second contoured member (15b), a contoured surface (22) of which contacts a cam (14) rotated by the actuating mechanism (12). A roller (20) is interposed between the first contoured member (15a) and the second contoured member (15b), and the spatial position of the roller is regulated by an actuating device (23, 25) to determine the law of movement of the valve (11). <IMAGE>
