Title
(JA) 制限流量による逆推力装置の作動
Abstract
(JA)

エンジン組立体は、エンジンを少なくとも部分的に囲むように構成されたナセルと、ナセルに連結された逆推力装置とを含む。逆推力装置は、格納位置と展開位置との間を、ナセルに対して移動可能な逆推力要素と、逆推力要素を動かすように作動可能に連結された液圧のアクチュエータと、液圧のアクチュエータを作動させるように構成された流体制御システムとを含む。流体制御システムは、加圧流体源と、アクチュエータと、流体戻りリザーバとの間で流体を選択的に送るように作動可能な方向制御弁を含む方向制御部と、方向制御弁と無関係に、アクチュエータと流体戻りリザーバとの間の流体連通を提供する一つ以上のバイパス流路と、加圧流体源と方向制御弁との間にある流量制限器であって、アクチュエータによって引き込まれる圧力が所定の閾値を超えるのを阻止するように構成された流量制限器とを含む。
