Abstract (en)
The device is operable to allow the rise and phase of the valve (4) to be varied during operation of the engine (1) and is provided with a rocker (10) cooperating at one end (9) with a stem (5) of the valve (4) and at the other end (12) with an oscillating cam (14) of predetermined shape driven by a cam follower (24) slidable in a seat (25) and cooperating with a rotating cam (26) of predetermined shape. The cam follower (24) receives translational movement from the rotating cam (26) and transmits a reciprocating movement to the oscillating cam (14) and the rocker (10), and is operable to vary its length between two end positions to vary the timing and rise of the valve (4).
