Beschreibung
Zusammenfassung:	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; an additional shaft (12) provided with one or more additional cams (13), suitable to determine the motion of the actuator system, so that in a first position (A) of the additional shaft (12), the additional rocker arm (9) does not come into contact with the additional cams (13), and in a second position (B) of the additional shaft (12), the additional rocker arm (9) comes into contact with the additional cams (13) to determine the actuation of the engine brake.
