摘　　要：为了提高先导压力稳定性,针对溢流阀组原理及问题进行分析,并研究了一种新型的泄油口外置式溢流阀组结构。通过测试结果对比可知,该结构溢流阀组显著提高了系统使用性能及稳定性,并降低了能量损失。In order to improve the stability of the pilot pressure, the paper analyzed the principle and problems of the relief valve group, and studied the structure of a new-type relief valve group with external drainage port. Comparison of test results showed： the relief valve group remarkably enhanced the service performance and system stability, and energy loss reduced also.
