PROBLEM TO BE SOLVED: To provide a device for washing the supply flow passage and return flow passage of a hydraulic fluid pipe disposed in the airframe of an aircraft.SOLUTION: A wash device 10 comprises a washing agent circulation device 12; a valved connecting conduit; a connecting conduit on-off valve; and a control unit 14. Each of first and second hydraulic fluid pipes communicates with a plurality of equipment ends via a supply end and a T branch portion. The washing agent circulation device 12 includes a supply flow passage 31 for supplying a washing agent; and a return flow passage 32 for returning the washing agent. The valved connecting conduit connects an equipment end of the first hydraulic fluid pipe to an equipment end of the second hydraulic fluid pipe. The connecting conduit on-off valve is disposed halfway in the valved connecting conduit, controls a flow rate of the washing agent flowing in the valved connecting conduit on the basis of a command of the control unit 14, and simultaneously washes the first and second hydraulic fluid pipes of an aircraft.SELECTED DRAWING: Figure 18

    【課題】航空機の機体に配置される作動油配管の供給流路及び戻り流路を短時間で洗浄する装置を提供する。【解決手段】洗浄装置10は、洗浄剤循環装置12と弁付連結管と連結管開閉弁と制御部14とを備える。第1及び第2作動油配管は、供給端及びT分岐部を介して複数の装備品端に連通する。洗浄剤循環装置12は、洗浄剤を供給するための供給流路31と、洗浄剤を戻すための戻り流路32とを有する。弁付連結管は、第1作動油配管の装備品端と、第2作動油配管の装備品端との間を接続する。連結管開閉弁は、弁付連結管の途中に配置され、制御部14の指示に基づいて弁付連結管に流れる洗浄剤の流量を制御して、航空機の第1及び第2作動油配管を同時に洗浄する。【選択図】図18
