In a valve drive train actuating device, particularly for an internal combustion engine, having at least one firing camshaft, which can be phase shifted relative to a crankshaft by a firing camshaft adjusting device and a decompression brake device comprising at least one brake cam and at least one decompression valve, the valve drive train actuating device comprises an adjusting device for adjusting a decompression valve drive actuating point in time depending on the speed of the crankshaft of the engine such that, with decreasing speed of the crankshaft, the brake cam actuating point is moved toward the upper dead center position of the crankshaft.

Valve drive train actuating device

In a stroke-transmitting device for a variable transmission of an operating stroke to a member to be actuated, specifically a gas exchange valve for an internal combustion engine, including a control unit with first and second control structures, a control cam is provided for coupling the first and second control structures and having different control regions which are displaceable for an adjustment of the stroke of the member to be actuated with at least first and second degrees of freedom for controlling the stroke transmitted to the member to be actuated.

Stroke-transmitting device

In a gas exchange valve actuating device having a lever for transmitting a drive movement to at least one gas exchange valve of an engine braking control unit of an internal combustion engine, the internal combustion engine includes a compact braking control unit which is coupled to the valve operating lever for controlling actuation of the gas exchange valves in a braking mode of engine operation.
