液(ye)(ye)壓(ya)傳動(dong)是(shi)(shi)以(yi)液(ye)(ye)體為工(gong)作介(jie)質，利用液(ye)(ye)體的(de)壓(ya)力(li)能(neng)來實現運動(dong)和(he)力(li)的(de)一種(zhong)(zhong)傳動(dong)方式(shi)。一般而(er)言，能(neng)夠實現某種(zhong)(zhong)特定功能(neng)的(de)液(ye)(ye)壓(ya)元(yuan)(yuan)(yuan)(yuan)件(jian)的(de)組合，稱為液(ye)(ye)壓(ya)回路，而(er)若干特定的(de)基本功能(neng)回路連接或復合而(er)成的(de)總體則(ze)稱為直流液(ye)(ye)壓(ya)動(dong)力(li)單元(yuan)(yuan)(yuan)(yuan)。直流液(ye)(ye)壓(ya)動(dong)力(li)單元(yuan)(yuan)(yuan)(yuan)通常都是(shi)(shi)由液(ye)(ye)壓(ya)元(yuan)(yuan)(yuan)(yuan)件(jian)（動(dong)力(li)元(yuan)(yuan)(yuan)(yuan)件(jian)、執行元(yuan)(yuan)(yuan)(yuan)件(jian)、控制元(yuan)(yuan)(yuan)(yuan)件(jian)、輔助元(yuan)(yuan)(yuan)(yuan)件(jian)）和(he)工(gong)作介(jie)質兩大(da)部分組成。
