Leading to the circuit by hydraulic cylinder block, cylinder pressure access to oil, so do not stop moving table; if pushed to the right spool (the location of the right side of work), then valve port P and A, B and T connected, the pressure of oil by the P I Inflow valve 6, by influx of population A hydraulic cylinder 8 of the left cavity, the piston 9 in the left cavity pressure hydraulic cylinders, driven by oil-led move to the right table 10; hydraulic cylinder the right cavity of the oil through the valve 6 b I 6 flows to the valve, but also by the return oil flows back to tank T I 1; if the spool valve 6 onto the left, piston table to the left-led movement; thus reversing the work of 6 different locations, changing the pressure of the oil will be able to access, so that constantly change to the hydraulic cylinder in order to achieve the required table reciprocating motion.
通向液压缸的油路被堵死，液压缸不通压力油，所以工作台停止不动；若将阀芯向右推，这时阀口P和A，B和T相通，压力油经P口流人换向阀6，经A口流入液压缸8的左腔，活塞9在液压缸左腔压力油的推动下带动工作台10向右移动；液压缸右腔的油液通过换向阀6的b口流入到换向阀6，又经回油口T流回油箱1；若将换向阀6的阀芯向左推，活塞带动工作台向左移动；因此换向阀6的工作位置不同的，就能不断改变压力油的通路，使液压缸不断换向，以实现工作台所需要的往复运动。

利用液压泵保压的保压回路也就是在保压过程中，液压泵仍以较高的压力工作，此时，若采用定量泵，则压力油几乎全经溢流阀流回油箱，系统功率损失大，易发热，故只在小功率的系统且保压时间较短的场合下才使用；若采用变量泵，在保压时，泵的压力较高，但输出流量几乎等于零。
