The device has a tilt lever (2) connected on one side via a valve actuating bridge (4) to a delay device (E) and on the other directly to a play compensating telescopic device (T) on a push rod (1). The delay device has a cylindrical bush (Z) on the actuation bridge, a final control piston on a fixed guide rod and an annular chamber (8) for lubricating oil connected by oil lines (9,11,19) to valve units (V,V1) during the inlet valve (7) opening and/or closing process.
