    The invention relates to engine-building and permits an increase in the accuracy of control of valves in controlled valve timing mechanisms. The device contains inlet and exhaust valves 1 driven by hydraulic cylinders 6 with pistons 7 and a valve control system with a spool device equipped with a rotating spool 13 and distribution sleeves 11 and 12. With axial displacement of the spool 13, the lift height of the valves is controlled, and by relative reversing the distribution sleeves 11 and 12 by means of a differential gear with gears 37 and 38, control of the valve overlap value is achieved. This ensures optimum valve timing for various engine operating conditions. 4 hp f-ly, 8 ill. And a Ј (L
