Abstract
In an operating mechanism for an engine brake valve of an internal combustion engine which has fuel injectors mounted in the cylinder head to which pressurized fuel is delivered through high pressure fuel passages from a high pressure fuel injection pump, a hydraulic operating piston disposed in a hydraulic cylinder is operatively connected to the engine brake valve by way of a lever which is actuated by the hydraulic operating piston when fuel under pressure is supplied to the hydraulic cylinder and a hydraulic control valve is arranged in the high pressure fuel passages for selectively directing the high pressure fuel from the injection pump either to the injector for injection into the engine or to the hydraulic cylinder for opening the engine brake valve at the end of an engine compression stroke to discharge the compressed gas from the engine during engine braking operation.
