る、マスターバルブ式圧縮ブレーキ装置。 A compression brake device attached to an engine includes a third valve capable of discharging a required amount of combustion gas in a combustion chamber for braking, and an opening/closing drive mechanism that opens and closes the third valve at a required timing. A driving mechanism includes a master valve installed in a cylinder head and driven near the compression top dead center of the engine, a first cylinder incorporating a piston that is pressed by the driving of the master valve, and the first cylinder. and a second cylinder containing a piston that is moved by being supplied with working fluid, and the third valve is connected to the piston of the second cylinder so as to be linked to the piston. A master valve type compression brake device.
