Abstract: A fluid pressure control device includes a first circuit system having a first pump and a first control valve. The first circuit system includes an intermediate cut valve provided downstream of the first control valve in a first intermediate passage and which connects and disconnects a connection between the first intermediate passage and the tank, and an external output port communicating at a part downstream of the first control valve in the first intermediate passage and upstream of the intermediate cut valve, the external output port being capable of externally supplying working fluid discharged from the first pump.

Abstract: A fluid pressure control device includes a first tank passage connecting first tank ports to each other, a second tank passage connecting second tank ports to each other, a connection passage connecting one end side of the first tank passage and one end side of the second tank passage and a discharge port provided on the other end side of the first tank passage and connected to a tank. A communication spool formed with a communication passage allowing communication between the first tank passage and the second tank passage is housed in at least one of a plurality of spool housing holes.
