當機(ji)上液壓(ya)泵10或(huo)三位(wei)四通(tong)電(dian)磁(ci)閥(fa)(fa)1等(deng)出(chu)現故(gu)障時(shi)，應(ying)急油(you)源9通(tong)過(guo)單(dan)向(xiang)閥(fa)(fa)8直接(jie)到作動筒的右腔，使作動筒活塞桿16縮回；同(tong)時(shi)應(ying)急油(you)源9打(da)開(kai)液控(kong)單(dan)向(xiang)閥(fa)(fa)3，使作動筒的左(zuo)腔直接(jie)與液壓(ya)泵10的回油(you)相接(jie)。

當高壓油經閥塊組件(jian)26進入作動(dong)(dong)(dong)筒伸(shen)出(chu)腔，推(tui)動(dong)(dong)(dong)活塞(sai)(sai)(sai)桿16向(xiang)右(you)運動(dong)(dong)(dong)，內置(zhi)卡環鎖20同時(shi)向(xiang)右(you)移動(dong)(dong)(dong)，當卡環運動(dong)(dong)(dong)到(dao)外筒內表面直徑(jing)增大(da)處(chu)時(shi)，卡環因自身的彈簧(huang)張(zhang)力張(zhang)開(kai)，恢復到(dao)自由未(wei)壓縮狀態(tai)，高壓油繼(ji)續推(tui)動(dong)(dong)(dong)游動(dong)(dong)(dong)活塞(sai)(sai)(sai)右(you)移，于(yu)是(shi)游動(dong)(dong)(dong)活塞(sai)(sai)(sai)凸部插入卡環內徑(jing)里，制(zhi)止卡環收(shou)縮。同時(shi)，鋼球從中位(wei)(wei)狀態(tai)移入游動(dong)(dong)(dong)活塞(sai)(sai)(sai)左(zuo)端槽內，定位(wei)(wei)彈簧(huang)回位(wei)(wei)使其(qi)兩套筒之間距離減小，也同時(shi)推(tui)動(dong)(dong)(dong)鋼球上(shang)升到(dao)孔內并頂住鋼球不下(xia)落，以實現伸(shen)出(chu)位(wei)(wei)置(zhi)的上(shang)鎖。此時(shi)，伸(shen)出(chu)位(wei)(wei)置(zhi)微動(dong)(dong)(dong)開(kai)關7被觸動(dong)(dong)(dong)，飛機上(shang)信號燈顯示為伸(shen)出(chu)到(dao)位(wei)(wei)。

雙向液壓(ya)鎖5在開鎖時，高壓(ya)油(you)經閥(fa)塊進(jin)入(ru)作動(dong)(dong)筒縮(suo)回(hui)腔，首先推動(dong)(dong)游(you)動(dong)(dong)活(huo)塞(sai)左移推出(chu)卡(ka)(ka)環之外，同時，液壓(ya)力克服彈簧(huang)彈力而(er)(er)壓(ya)縮(suo)彈簧(huang)，使其(qi)鋼球(qiu)下移，從而(er)(er)順(shun)利推出(chu)游(you)動(dong)(dong)活(huo)塞(sai)，然后，液壓(ya)力迫使卡(ka)(ka)環壓(ya)縮(suo)縮(suo)小(xiao)，并推動(dong)(dong)卡(ka)(ka)環進(jin)入(ru)外筒直徑減(jian)小(xiao)段，以實現縮(suo)回(hui)位(wei)(wei)置的開鎖。此時，縮(suo)回(hui)位(wei)(wei)置微動(dong)(dong)開關12被(bei)觸動(dong)(dong)，飛機上信號燈(deng)顯示為縮(suo)回(hui)到位(wei)(wei)。活(huo)塞(sai)桿16縮(suo)回(hui)時的開鎖、上鎖方式與之相反。
