8 2 , and an operation valve 11 that connects and controls the first and second main circuits a and b, which are equipped with check valves 16 and 20, to the fluid pressure source 10 and the tank 14, and the first and second main circuits. Due to the pressure difference between a and b, one side position and the other side position will block the flow of return fluid from one main circuit, and when there is no pressure difference, the flow of return fluid from both main circuits will be blocked. A control valve 22 located at the center; a bypass path 23 that short-circuits the check valves 16 and 20 closer to the fluid motor 18 in the first and second main circuits a and b; 2 safety valve 2
4, 25, the first safety valve 24 is set to high pressure with the high pressure fluid of the second main circuit b, and the second safety valve 25 is set to high pressure with the high pressure fluid of the second main circuit a.
A fluid brake device characterized in that a high pressure is set with a high pressure fluid, and a portion of a bypass passage 23 between a first and second safety valve 24 and 25 is connected to a low pressure side through a throttle.
