Patent attributes
A decompression braking device in an endothermic engine (1) is provided of the type comprising a lever axle (2) on which a plurality of eccentric bushings (31) of a corresponding plurality of levers (3) provided with tappets (4) are rotationally and eccentrically mounted for actuating a plurality of exhaust valves (5), and a camshaft (30) for actuating the plurality of levers (3), the device is characterized in that it comprises an actuating member (6, 61) mounted externally to the lever axle (2) and connected to the latter by linkages (8, 9, 10), such that a respective rotation of the bushings (31) by a predetermined angular value (α), with consequent displacement of the hinging axis of the levers (3), corresponds to each excursion of the actuating member (6, 61).
