Abstract:
A fluid control device provided with a plurality of switching valves and a plurality of relief valves. A sub-relief passage communicating with a tank when the switching valves are in any state other than neutral is branched from a parallel passage for guiding a high-pressure hydraulic fluid to the switching valves. A sub-relief valve is provided within the sub-relief passage, and a check valve that minimizes the flow of hydraulic fluid toward a hydraulic pressure supply source is provided between switching valves and the point of branching of the sub-relief passage in the parallel passage

Claim (Index 2):
A fluid control device comprising:\n a plurality of switching valves; a high-pressure flow path which receives a supply of high-pressure hydraulic fluid from a hydraulic pressure supply source, and passes through the plurality of switching valves in a neutral state; a parallel flow path which branches from the high-pressure flow path to direct the hydraulic fluid to each of the switching valves; a return flow path which receives and directs the hydraulic fluid having passed through all the switching valves via the high-pressure flow path and the hydraulic fluid discharged from each switching valve to a tank; a main-relief passage through which a part between the hydraulic pressure supply source and the switching valve located on a most upstream side communicates with the return flow path; a main-relief valve which is provided in the main-relief passage and opens when the fluid pressure of the high-pressure flow path exceeds a predetermined first fluid pressure; a sub-relief passage which branches from the parallel passage, reaches the switching valve, and communicates with the tank when the switching valve is in a predetermined state other than the neutral state; a sub-relief valve which is provided in the sub-relief passage, and opens when the fluid pressure of the parallel flow path exceeds a second fluid pressure lower than the first fluid pressure; and a check valve which suppresses the flow of hydraulic fluid toward a hydraulic pressure supply source provided between the branch with the sub-relief passage and the switching valve in the parallel passage.
