。When the cylinder of an internal combustion engine reaches the vicinity of compression top dead center, the valve is opened for a predetermined period of time by a valve driving means to absorb the compression work, and the valve driving means pressurizes from the engine oil pan by the movement of a cam. A pressure pump that supplies pressurized oil to the valve operating piston of the cylinder is connected in the oil system path between this pressure pump and the valve operating piston, and is closed when the pressure oil is pumped to the operating piston to create negative pressure on the cam. An engine brake device characterized by comprising a check circuit that opens when pressure oil is sucked from a valve operating piston by action to guide oil from an engine oil pan to a pressure pump.
