Abstract: A valve actuation mechanism for an internal combustion engine includes rockers moved by a camshaft, each rocker being adapted to exert a valve opening force on at least a portion of a valve opening actuator of each cylinder, via an activation piston, housed in a bore of the rocker and movable with respect to the rocker under action of a fluid pressure raise in a chamber fluidly connected to the bore, from a first position to a second position with respect to the rocker, in which a cam follower of the rocker is adapted to read at least one auxiliary valve lift sector of a cam of the camshaft so as to perform an engine operating function. Each rocker includes a check valve adapted to control the fluid pressure raise in the chamber. The valve actuation mechanism includes, for each rocker, a stopper fast with a housing of the engine and adapted to exert, on a member of the rocker, a force for opening a valve independent from the check valve, adapted to release fluid from the chamber when the piston has to be moved from its second position to its first position.

Abstract: A valve actuation mechanism for an internal combustion engine includes rockers moved by a camshaft, each rocker being adapted to exert a valve opening force on at least a portion of a valve actuation mechanism of each cylinder belonging to a housing of the engine, via an engine brake activation piston, housed in a bore of the rocker, and movable with respect to the rocker under action of a fluid pressure raise in a chamber fluidly linked to the bore, from a first position, in which an engine brake function is deactivated, to a second position, in which a roller of the rocker reads at least one engine brake bump of a cam of the camshaft so as to perform the engine brake function. Each rocker includes a discharge valve movable in translation with respect to the rocker, adapted to reduce fluid pressure in the chamber. The engine brake system includes, for each rocker, a stopper fast with the housing and adapted to exert, on a portion of the piston, a force for opening the discharge valve when the activation piston has to be moved from its second position to its first position.
