ようにしたことを特徴とする排気ブレーキ弁。 A bypass pipe line that bypasses the upstream side and the downstream side of the butterfly valve, and a relief valve inserted into the bypass line, and when the pressure on the upstream side of the butterfly valve increases due to throttling of the butterfly valve, the pressure is increased. An exhaust brake valve characterized in that when the pressure rise exceeds a set pressure of the relief valve, a part of the fluid on the upstream side of the butterfly valve bypasses the butterfly valve via the bypass pipe.
