先導(dǎo)溢流閥的主閥上腔壓力，是由先導(dǎo)閥加于控制的。如果先導(dǎo)閥正常工作，即主閥上腔有先導(dǎo)閥規(guī)定的壓力，則整個(gè)溢流閥就會(huì)在系統(tǒng)壓力到達(dá)調(diào)定壓力時(shí)其主閥口打開(kāi)一定的開(kāi)度，一方面能將系統(tǒng)多余流量流回油箱，另一方面又能維持系統(tǒng)的壓力為先導(dǎo)閥的調(diào)定值。可見(jiàn)，先導(dǎo)閥主要管壓力，主閥服從先導(dǎo)閥的領(lǐng)導(dǎo)，在先導(dǎo)閥動(dòng)作時(shí)將主閥口開(kāi)到合適大小，正好將多余流量流出去，又不影響系統(tǒng)壓
