Date Feb. 16, 1995A rocker assembly includes a central arm and two outer arms supported on a rocker shaft portion, and a plurality of supporting brackets. The arms, which are actuated by respective cams, actuate at least two lifting valves of a cylinder of an internal combustion engine. Both outer arms may be independently hydraulically coupled by bolt elements to the central arm. Hydraulic ducts extend through the supporting brackets, the rocker shaft portion and the outer arms to communicate with the coupling bolts. The rocker arms, the rocker shaft portion, and the supporting brackets form a pre-assembly unit. The central arm may have a roller on which an associated cam rolls, with the bolt elements of the central arm being arranged coaxially to the roller inside the roller.
