PV7 系列标准单泵可相互组合成组合泵，也可与内齿轮泵、外齿轮泵、轴向柱塞泵和径向柱塞泵组合。
用于连续运行中对容积流量的要求可变、保压功能百分比较高的驱动器，如：
机床
静液压轴承
恒压系统
PV7... 型号叶片泵的可调节排量有助于实现低脉动流量并可在下行控制过程中达到非常高的重复精度和低压力峰值，这些均得益于其特殊设计。通过调整高度调节螺钉实现噪音优化，从而降低工作噪音。流体动力润滑的滑动轴承确保长久使用寿命。排液器的轴向补偿可实现佳的容积效率。
功能，横截面
型号 PV7 的液压泵是具有可变排量的叶片泵。
基本上由壳体、转子、叶片、定子环、压力控制器和容量调节螺钉组成。
圆形定子环 由小型往复式控制活塞和大型往复式控制活塞支撑。环的第三个支撑点是高度调节螺钉。
驱动转子在定子环 中旋转。在离心力的作用下，转子 中的导向叶片 贴紧定子环 的内滑动面。
吸油和排油过程
运输液压油的必要元件由叶片、转子、定子环 和控制板组成。
为保护调试过程中的泵功能，定子环 由位于大驱动柱塞后的弹簧支持，保持其偏心位置（排液器位置）。
转子 旋转时元件容积增加，且元件通过吸油通道填充液压油。达到大元件容积后，元件将与吸油侧分离。如果转子 进一步旋转，则会建立与压力侧的连接，元件将会减少液压油并通过压力通道将其压入系统中。
调节
随着压力在系统中积聚，小型控制柱塞的后侧始终通过通道向系统压力加压。
在排放位置，大型控制柱塞的后侧也通过控制阀芯中的钻孔向系统压力加压。具有较大面积的控制活塞将定子环 保持在其偏心位置。
泵以低于压力控制器上设定的零行程压力的压力排出液压油。
控制阀芯由弹簧保持在某一位置。
下行控制
如果产生自产品压力 x 面积的力 FP 超过了弹簧的反作用力 FF，调节器阀芯则会向弹簧偏移。因此，位于大驱动柱塞后的腔体将与油箱连接，从而进行卸载。
连续受到系统压力作用而被加压的小驱动柱塞会将定子环 移至几乎接近中心位置。泵保持压力不变，流量降至零且泄漏被取代。
液压油的功率损耗和热量即可保持为小。
特性曲线 qV-p 保持垂直，且在设置不同压力值时平行移动。
行程内控制
当系统中压力降至所设零行程压力以下时，弹簧会将控制阀芯推回其原位置。
再次对大控制活塞进行加压，并将定子环 移至偏心位置。泵再次开始排油。

型号 PV7 的液压泵是变量叶片泵。
主要由泵体、转子、叶片、定子环、压力控制器和调节螺栓组成。圆形的定子环夹持在小调节活塞和大调节活塞之间。此环的第三个接触点是高度调节螺栓。被驱动的转子在定子环内转动。转子槽内的叶片由于离心力的作用压在定子环上。

力士乐REXROTH叶片泵吸油和排油过程
用来传递油液的腔由叶片、转子、定子环和配油盘形成。
为了在投入使用时确保泵的运行功能，定子环由大调节活塞后面的弹簧压在其偏心位置 (排油位置)。

当转子转动时，油腔的容积增大，并且通过吸油通道吸油。当油腔达到大容积时，它脱离吸油侧。转子继续转动，此腔和压油侧接通，并使其容积减小，通过压油通道压油到系统。

类型 PV7...A 液压泵是直动式叶片泵，其排量体积可调。
基本上由壳体，盖板，转子，叶片，定子环，压缩弹簧，调整螺钉和控制板组成。为限制大流量，该泵配有调节螺钉。驱动转子在定子环中旋转。转子中导入的叶片在离心力的作用下贴紧定子环的内跑合面。
吸油和排油过程
运输流体所需的腔室由叶片，转子，定子环，控制板和盖板组成。
转子旋转时室体积增加，腔室通过吸油通道填充流体。达到大室体积后，腔室从吸油侧分离。
随着转子继续旋转，高压流体侧的连接打开，腔室缩小并迫使流体通过压力油口进入系统。
压力控制
定子环由弹簧固定在其初始的偏心位置。系统中所需的大工作压力是在调节螺钉处通过弹簧设定。增大的压力是由于对抗弹簧力的工作阻力作用于定子
环内跑合面的压力侧而产生的。
达到相关压力（由设定的弹簧力决定）后，定子环朝零位置的方向移出其偏心位置。流量自我调节至当时所需的值。当达到
弹簧处设置的大设定压力时，泵会将流量调回至几乎为零。工作压力得到保持，且仅更换泄露流体。流体的损失和加热从而降至低水平。
