Abstract
A device for actuating the decompression engine brake in an internal combustion engine provided with hydraulic tappets is described, characterized by: an additional rocker arm (9) for each cylinder, pivoting about an axis (4) common to the rocker arms of the exhaust valves, and suitable to engage with a corresponding additional cam (10) arranged on the cam axis (7) of the cylinders; an actuator system for said additional rocker arm (9), for each cylinder. In the actuator system of said additional rocker arm (9) there is a piston (15) hinged to an end of said rocker arm, said piston (15) being in its turn moved hydraulically or by a mechanical system comprising an additional arm (12) controlled by eccentric cams (13).
