Fluid pressure control device

A fluid pressure control device, comprising:

• a first main passage to which a working fluid is supplied from a first pump port;
• a second main passage to which the working fluid is supplied from a second pump port;
• a plurality of first work control valves for work devices connected to the first main passage in parallel;
• a plurality of second work control valves for work devices connected to the second main passage in parallel;
• a first travel control valve for a travel device connected to the first main passage in parallel at an upstream of the first work control valves;
• a second travel control valve for a travel device connected to the second main passage in parallel at an upstream of the second work control valves;
• a first switching valve provided on a downstream of a connection portion with the first travel control valve in the first main passage and having an open position where the first main passage is opened and a first priority position where the working fluid from the first pump port is led to the first travel control valve with priority;
• a second switching valve provided on a downstream of a connection portion with the second travel control valve in the second main passage and having an open position where the second main passage is opened and a first priority position where the working fluid from the second pump port is led to the second travel control valve with priority;
• and
• a merging passage connecting a downstream of the first switching valve in the first main passage and a downstream of the second switching valve in the second main passage, wherein
• in a state where the first work control valves and the second work control valves are not operated and the first travel control valve is operated, the first switching valve is at the first priority position;
• and
• in a state where the first work control valves and the second work control valves are not operated and the second travel control valves is operated, the second switching valve is at the first priority position.
