ATOS液壓泵的性(xing)能(neng)參(can)數，主(zhu)要有以下這(zhe)幾(ji)個

 　　ATOS液壓泵是(shi)活(huo)塞或(huo)柱塞的往(wang)復運動(dong)方(fang)向與(yu)缸(gang)體(ti)中(zhong)軸(zhou)平行(xing)的柱塞泵，它都是(shi)依(yi)靠(kao)密封容積(ji)變革的事(shi)理來結(jie)束工(gong)作(zuo)的，故(gu)同(tong)樣(yang)平(ping)凡(fan)稱(cheng)為(wei)容積(ji)式(shi)液壓泵，單(dan)柱塞液壓泵的工(gong)作(zuo)事(shi)理圖(tu)柱塞2裝(zhuang)在(zai)缸(gang)體(ti)3中(zhong)組(zu)成壹個密封容積(ji)a，柱塞在(zai)彈(dan)簧(huang)4的浸(jin)染下(xia)不停(ting)壓緊(jin)在(zai)偏(pian)心輪1上(shang)。原動(dong)機(ji)驅動(dong)偏(pian)心輪1旋轉(zhuan)使(shi)柱塞2作(zuo)往(wang)來來往(wang)運(yun)動，使(shi)密封容積(ji)a的大(da)小(xiao)發生周期性(xing)的瓜(gua)代(dai)變革。
