疊加一個P口可調(diào)節(jié)流閥：控制油先通過疊加可調(diào)節(jié)流閥、到達(dá)電磁先導(dǎo)閥的P口，通過電磁先導(dǎo)閥的換向及調(diào)整節(jié)流閥的開度，來實現(xiàn)主閥芯的換向延時，從而達(dá)到降低主油路與執(zhí)行元件接通時的換向沖擊。但先導(dǎo)電磁閥斷電時、彈簧復(fù)位型電液換向閥主閥體兩端蓋內(nèi)的液壓油會通過先導(dǎo)電磁閥的中位與泄油口接通、主閥芯在復(fù)位彈簧的作用下會立即復(fù)位，由于主閥芯復(fù)位快、亦即切斷執(zhí)行元件油路的速度快、從而引起液壓沖擊。由此可見，疊加一個P口可調(diào)節(jié)流閥，只能實現(xiàn)換向接通延時、不能解決復(fù)位切斷延時。注：象油缸類的執(zhí)行元件，油缸前進(jìn)與后退時通過換向閥的流量是不一致的，油缸無桿腔與有桿腔的面積比越大、流量差距也越大，此時若想較滿意的降低執(zhí)行元件前進(jìn)與后退時的液壓沖擊，通過一個可調(diào)節(jié)流閥，恐怕是難以實現(xiàn)的。
