液压系统设计时为提高系统稳定性，减少负载变化对速度的影响，要么牺牲部分我们想实现的功能，要么增加额外的液压元件，如调速阀、压力控制阀等，通过增加阻尼，提高系统速度刚度来提高系统的稳定性。但是这样元件的增加又会降低效率，浪费能源；还会使得整个系统的可靠性降低、增加成本。 R900424371 ZDR6DA3-4X/210Y

（2）由于换向结构的特殊性，使得用户在实现某一功能时必须购买相应的液压元件，再加上工程机械厂家会根据不同最终用户要求设计出相应的功能，这样会造成生产厂家采购同类、多规格的液压控制元件来满足不同功能要求的需要，不利于产品通用化及产品管理，同时会大大提高产品成本。LFA80H2-6X/F

（3）由于执行机构进出液压油通过一根阀芯进行控制，单独控制执行机构两侧压力是不可能的。因此，出油侧背压作用于执行机构运动的反方向，随着出油侧背压升高，为保质执行机构的运动，必须提高进油侧压力。这样会使得液压系统消耗的功能增加，效率低，发热增加。 一步升高。
弹簧腔经孔至洞口T（Y）由外部泄油至油箱。压力表接口用于阀的二次压力监测。
DP和DB型
在DP型中，油口P1减压。信号和控制油从油口P1内部提供。在DB型中，油口P1减压但控制油取自B。
注意！
在DB型中，当方向阀处于P至A位置时，必须确保油口B的压力不高于设定压力。否则油口的压力将降低。

采用双阀芯技术的液压系统，由于执行机构进出油侧阀口阀芯位置及控制方式各自独立，互不影响，这样通过对两阀芯控制方式的不同组合，利用软件编程能很好解决传统单阀系统不能解决的问题，同时还可以轻易实现传统液压系统中难以实现的功能。

在驱动轴驱动轴 （1） 的齿上安装有转子 （2），它在定子环 （3） 内回转。叶片 （4） 安装在转子槽内，转子转动时靠离心力使叶片压在定子环的内表面。排油腔的端面由配油盘 （5） 密封。由于定子环是双偏心结构，因此形成对称布置的两个吸油区和两个压油区，因此传动轴的径向液压力相互平衡而卸载。轴仅传递驱动转矩。在吸油区，叶片部分地卸荷。这能减少磨损和获得高效率。取下端盖 （6），可以更换泵芯 （由转子、叶片、定子环和配油盘组成），而不必从钟形罩上卸下泵体 （7）。这样就能迅速地对泵进行维护和修理。
