摘要： A hydraulic control apparatus includes: a plurality of spools incorporated into a valve main body; a cap provided on the valve main body; pilot chambers provided in the cap to correspond to the respective spools; a maximum pressure introduction passage to which a maximum pressure of the pilot chambers is led; connecting passages connecting the maximum pressure introduction passage to the respective pilot chambers; and selection valves provided in the connecting passages. The maximum pressure of the respective pilot chambers is selected by the selection valve and led to the maximum pressure introduction passage. The maximum pressure introduction passage is provided in the cap on an opposite side of the pilot chambers to a side on which the valve main body is provided.

摘要： A control valve apparatus includes a second-working-actuator acceleration control valve connected to a first working control valve in parallel. The second-working-actuator acceleration control valve includes pilot chambers receiving a pilot pressure for switching first and second working control valves and a flow channel that guides a pressure fluid of a first pump port to an entrance port side of the second working control valve. The second-working-actuator acceleration control valve is switchable between a first priority position in which a pressure fluid is guided to the first working control valve with a higher priority than the second working control valve and a second priority position in which a pressure fluid is guided to the second working control valve with a higher priority than the first working control valve.

摘要： A travel control valve includes a valve body and a spool. The valve body includes a first pump port connected on an upstream side from a drive control valve, a first connection port connected on a downstream side from the drive control valve, a second pump port connected to a second pump, and a second connection port connected to a second circuit system. The travel control valve can switch a communication opening between the first pump port and the first connection port to a large opening throttle position in which the communication opening remains smaller than that between the second pump port and the second connection port, and a small opening throttle position in which the communication opening remains smaller than that in the large opening throttle position.
