PROBLEM TO BE SOLVED: To provide a hydraulic valve for an aircraft capable of suppressing an increase in size even if a flow rate of oil in a hydraulic servo mechanism is increased.SOLUTION: A hydraulic valve 20 includes: a first port 31 connected to a first hydraulic chamber of a hydraulic actuator that drives a wing; a second port 32 connected to a selector valve that bypasses the second hydraulic chamber and the first hydraulic chamber of the hydraulic actuator; a housing 30 where an oil passage 37 connecting the first port 31 and the second port 32; a check valve 67 for blocking the oil flow from a first port 31 side to a second port 32 side in the oil passage 37; a valve opening element 40 for opening the check valve 67 by pilot pressure supplied from the second hydraulic chamber; and an auxiliary oil passage 38 as auxiliary hydraulic pressure supply means for taking out the hydraulic pressure for opening the check valve 67 from a closed hydraulic pressure part 37A which is a part on a first port 31 side of the oil passage 37 with respect to the check valve 67.SELECTED DRAWING: Figure 2

    【課題】油圧サーボ機構の油を大流量化しても大型化を抑制することが可能な航空機用油圧バルブを提供する。【解決手段】油圧バルブ20は、翼を駆動する油圧アクチュエータの第1油圧室に接続される第1のポート31、油圧アクチュエータの第2油圧室と第1油圧室とをバイパスする切替バルブに接続される第2のポート32、および、第1のポート31と第2のポート32とを繋ぐ油路37が形成されるハウジング30と、油路37における第1のポート31側から第2のポート32側への油の流れを遮断するチェック弁67と、第2油圧室から供給されるパイロット圧によりチェック弁67を開弁する開弁要素40と、チェック弁67を開弁させる油圧を油路37のうちのチェック弁67よりも第1のポート31側の部分である閉鎖油圧部分37Aから取り出す補助油圧供給手段としての補助油路38とを備える。【選択図】図2
