<p>PROBLEM TO BE SOLVED: To dispose a maximum pressure introduction passage while keeping a degree of freedom in design.SOLUTION: A hydraulic control device includes: a plurality of spools incorporated in a valve body B; a cap C disposed on the valve body B; pilot chambers disposed in the cap C and corresponded to spools, respectively; a maximum pressure introduction passage 9 for guiding the maximum pressure among pressures of respective pilot chambers; a communication passage 10 communicating the maximum pressure introduction passage 9 with the respective pilot chambers; and a selection valve 11 disposed in the communication passage 10. The maximum pressure among pressures of the respective pilot chambers is selected by the selection valve 11 and guided to the maximum pressure introduction passage 9. The maximum pressure introduction passage 9 is disposed in the cap at a side opposite to a side of the valve body B, of the pilot chambers.</p> |
