二節(jié)同心結構:主閥芯為帶有圓柱面錐閥。為使主閥關閉時有良好密封性，要求主閥芯1圓柱導向面和圓錐面與閥套配合良好，兩處同心度要求較高，故稱二節(jié)同心。主閥芯上沒有阻尼孔，而將三個阻尼孔分別設閥體和先導閥體上。其工作原理與三節(jié)同心先導型溢流閥相同，只油液從主閥下腔到主閥上腔，需三個阻尼孔。

根據零件技術要求，進行動力和運動分析，再確定主要參數，液壓圖形編制，然后擬定液壓系統圖，進行標準元件選擇和元件設計，之后驗證液壓系統技術性能，zui后編制技術文件與審核。

ATOS先導型溢流閥特點：

1）、具有良好的自適應性能，布局靈活方便；
2）、單位功率的重量輕，工作平穩(wěn)、快速性好；
3）、液壓元件的可靠性高，使用壽命長；
4）、液壓系統設計、制造、和使用維護方便；
5）、傳動效率偏低；
6）、造價較高；
7）、故障診斷困難；
