它是利用主閥芯兩端的壓力差來移動主閥芯，以改變閥口的開度，油腔e和進(jìn)油口P相通，C和回油口T相通，壓力油作用于主閥芯6的右端，同時經(jīng)阻尼小孔d流入閥芯左端，并經(jīng)小孔a作用于錐閥3上，當(dāng)系統(tǒng)壓力低于溢流閥的調(diào)定壓力時，錐閥3關(guān)閉，阻尼孔d沒有液流流過，主閥芯兩端液壓力相等，閥芯6在彈簧5作用下處于關(guān)閉位置；當(dāng)系統(tǒng)壓力升高并達(dá)到溢流閥的調(diào)定值時，錐閥3在液壓力作用下壓縮導(dǎo)閥彈簧2并使閥口打開。于是6腔的油液經(jīng)錐閥閥口和孔c流入T口，當(dāng)油液通過主閥芯上的阻尼孔d時，便產(chǎn)生壓差，使主閥芯兩端產(chǎn)生壓力差，在這個壓力差的作用下，主閥芯克服彈簧力和摩擦力向左移動，使閥口打開，溢流閥便實(shí)現(xiàn)在一定壓力下溢流。調(diào)節(jié)彈簧2的預(yù)壓縮量便可改變該疊加式溢流閥的調(diào)整壓力。
