美国PARKER派克先导式比例溢流阀芯在合力的作用下处于zui下端位置，阀口关闭。当进油压力增大到使先导阀打开时，液流通过主阀芯上的阻尼孔5、先导阀1流回油箱。由于阻尼孔的阻尼作用，使主阀芯6所受到的上下两个方向的液压力不相等，主阀芯在压差的作用下上移，打开阀口，实现溢流，并维持压力基本稳定。调节先导阀的调压弹簧9，便可调整溢流压力。 先导型溢流阀的结构图，其主阀芯为带有圆柱面的锥阀。为使主阀关闭时有良好的密封性，要求主阀芯1的圆柱导向面和圆锥面与阀套配合良好，两处的同心度要求较高，故称二节同心。主阀芯上没有阻尼孔，而将三个阻尼孔2、3、4分别设在阀体10和先导阀体6上。其工作原理与三节同心Parker派克RE*W系列先导式比例溢流阀相同，只不过油液从主阀下腔到主阀上腔，需经过三个阻尼孔。阻尼孔2和4相串联，相当三节同芯阀主阀芯中的阻尼孔，是半桥回路中的进油节流口，作用是使主阀下腔与先导阀前腔产生压力差，再通过阻尼孔3作用于主阀上腔，从而控制主阀芯开启。阻尼孔3的主要作用是用以提高主阀芯的稳定性，它的设立与桥路无关。 RE10M10T4SN1F0 RE10M10T4SN1F046 RE10M10T4SN1R0 RE10M10T4SN1R046 RE10M10W1SN1KWMRE10M10W1SN1KWM41 RE10M10W4SN1KWM RE10M10W4SN1KWM41 RE10M10W4SN1XWM RE10M10W4SN1XWM41 RE10M17T4SN1F0 RE10M17T4SN1F046 RE10M17T4SN1R0 RE10M17T4SN1R046 RE10M17W1SN1XWM RE10M17W1SN1XWM41 RE10M17W4SN1KWM RE10M17W4SN1KWM41 RE10M17W4SN1XWM RE10M17W4SN1XWM41 RE10M25T1SN1F0M RE10M25T1SN1F0M46 RE10M25T1SN1R0 RE10M25T1SN1R046 RE10M25T4SN1F0 RE10M25T4SN1F046 RE10M25T4SN1F0M RE10M25T4SN1F0M46 RE10M25T4SN1R0 RE10M25T4SN1R046 RE10M25W4SN1KWM RE10M25W4SN1KWM41 RE10M25W4SN1XWMRE10M25W4SN1XWM41 RE10M35T1SN1F0 RE10M35T1SN1F046 RE10M35T1SV1F0M RE10M35T1SV1F0M46 RE10M35T4SN1F0 RE10M35T4SN1F046 RE10M35T4SN1G0 RE10M35T4SN1G046 RE10M35W1SN1KWM RE10M35W1SN1KWM41 RE10M35W1SN1XWMRE10M35W1SN1XWM41 RE10M35W1SV1KWM RE10M35W1SV1KWM41 RE10M35W4SN1KWM RE10M35W4SN1KWM41 RE10M35W4SN1XWMRE10M35W4SN1XWM41 RE10M35W4SV1XWM RE10M35W4SV1XWM41 RE10R10W4SN1KW RE10R10W4SN1KW41 RE10R10W4SV1KWM RE10R10W4SV1KWM41 RE10R17T1SN1F0M RE10R17T1SN1F0M46 RE10R17T4SN1F0M RE10R17T4SN1F0M46 RE10R17T4SN1G0MRE10R17T4SN1G0M46 RE10R17T4SN1R0MRE10R17T4SN1R0M46 RE10R17W1SN1XWRE10R17W1SN1XW41 RE10R17W4SN1XW RE10R17W4SN1XW41 RE10R25T1SN1F0 RE10R25T1SN1F046 RE10R25T4SN1F0M RE10R25T4SN1F0M46 RE10R25W1SN1KWRE10R25W1SN1KW41 RE10R25W1SN1XWM RE10R25W1SN1XWM41 RE10R25W4SN1XWM RE10R25W4SN1XWM41 RE10R35T1SN1F0 RE10R35T1SN1F046 RE10R35T1SN1F0M RE10R35T1SN1F0M46 RE10R35T4SN1F0 RE10R35T4SN1F046 RE10R35T4SN1F0M RE10R35T4SN1F0M46 RE10R35W1SN1KW RE10R35W1SN1KW41 RE10R35W1SN1KWM RE10R35W1SN1KWM41 RE10R35W1SN1XWM RE10R35W1SN1XWM41 RE10R35W4SN1KW RE10R35W4SN1KW41 RE10R35W4SN1KWM RE10R35W4SN1KWM41 RE10R35W4SN1XWMRE10R35W4SN1XWM41 RE25M10W4SN1KWMRE25M10W4SN1KWM40 RE25M10W4SN1XWM RE25M10W4SN1XWM40 RE25M17T4SN1F0 RE25M17T4SN1F046 RE25M17W1SN1KWM RE25M17W1SN1KWM41 RE25M17W1SN1XWMRE25M17W1SN1XWM41 RE25M17W4SN1KWM RE25M17W4SN1KWM41 RE25M17W4SN1XWM RE25M17W4SN1XWM41 RE25M25T1SV1F0M RE25M25T1SV1F0M46 RE25M25T4SN1F0RE25M25T4SN1F046 RE25M25W1SN1XWM RE25M25W1SN1XWM41 RE25M25W4SN1KWMRE25M25W4SN1KWM41 RE25M25W4SN1XWM RE25M25W4SN1XWM41 RE25M35T4SN1F0M RE25M35T4SN1F0M46 RE25M35T4SN1R0M RE25M35T4SN1R0M46 RE25M35T4SV1F0M RE25M35T4SV1F0M46 RE25M35W1SN1XWM RE25M35W1SN1XWM41 RE25M35W1SV1KWMRE25M35W1SV1KWM41 RE25M35W4SN1KWMRE25M35W4SN1KWM41 RE25M35W4SN1XWM RE25M35W4SN1XWM41 RE25R10W4SV1KWMRE25R10W4SV1KWM41 RE25R17T1SN1F0M RE25R17T1SN1F0M46 RE25R25W1SN1KWRE25R25W1SN1KW41 RE25R25W1SN1XW RE25R25W1SN1XW41 RE25R25W1SN1XWM RE25R25W1SN1XWM41 RE25R35T1SN1F0MRE25R35T1SN1F0M46 RE25R35T1SN1R0 RE25R35T1SN1R046 RE25R35T1SN1R0M RE25R35T1SN1R0M46 RE25R35T4SN1F0 RE25R35T4SN1F046 RE25R35T4SN1F0M RE25R35T4SN1F0M46 RE25R35W1SN1KW RE25R35W1SN1KW41 RE25R35W1SN1XWMRE25R35W1SN1XWM41 RE25R35W4SN1KW RE25R35W4SN1KW41 RE25R35W4SN1KWM RE25R35W4SN1KWM41 RE25R35W4SN1XWM RE25R35W4SN1XWM41
