力士樂(lè)A4VG變量柱塞泵系列特點(diǎn)：
 斜盤式軸向柱塞變量泵，用于閉式回路靜液壓傳動(dòng);流量與驅(qū)動(dòng)轉(zhuǎn)速及排量成正比并可無(wú)級(jí)變量；流量隨斜盤擺角從零增加到其zui大值；使斜盤擺過(guò)中位可以平穩(wěn)改變液流流動(dòng)方向；易與各種控制和調(diào)節(jié)系統(tǒng)匹配的多種變量方式；泵在高壓油側(cè)配備兩個(gè)溢流閥來(lái)保護(hù)靜液壓傳動(dòng)（泵和馬達(dá)）免于超載；高壓溢流閥同時(shí)也具有補(bǔ)油閥的功能；內(nèi)置輔助泵用作補(bǔ)油泵和控制泵；zui高補(bǔ)油壓力由一個(gè)內(nèi)置補(bǔ)油溢流閥來(lái)限制；全系列帶有內(nèi)置壓力切斷閥；
力士樂(lè)A4VG變量柱塞泵系列典型應(yīng)用：混凝土泵車、重型液壓平板車、液壓泵站
