力士樂A4VG變量柱塞泵系列特點：
 斜盤式軸向柱塞變量泵，用于閉式回路靜液壓傳動;流量與驅(qū)動轉(zhuǎn)速及排量成正比并可無級變量；流量隨斜盤擺角從零增加到其zui大值；使斜盤擺過中位可以平穩(wěn)改變液流流動方向；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)配備兩個溢流閥來保護靜液壓傳動（泵和馬達）免于超載；高壓溢流閥同時也具有補油閥的功能；內(nèi)置輔助泵用作補油泵和控制泵；zui高補油壓力由一個內(nèi)置補油溢流閥來限制；全系列帶有內(nèi)置壓力切斷閥；
力士樂A4VG變量柱塞泵系列典型應用：混凝土泵車、重型液壓平板車、液壓泵站
