当上行到柱塞上的斜槽（停供边）与套筒上的回油孔相通时，泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通，油压骤然下降，出油阀在弹簧力的作用下迅速关闭，停止供油。此后柱塞还要上行，当凸轮的凸起部分转过去后，在弹簧的作用下，柱塞又下行。此时便开始了下一个循环。柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀打开，液体进入；柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀打开，液体排出。柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单。 油压骤然下降，出油阀在弹簧力的作用下迅速关闭，停止供油，此后柱塞还要上行，当凸轮的凸起部分转过去后，在弹簧的作用下，柱塞又下行，此时便开始了下一个循环，柱塞泵以一个柱塞为原理介绍，一个柱塞泵上有两个单向阀。

即Fn/Ff=1.05~1.1，使泵工作正常并保持较高的容积效率。5．振动和噪声5．振动和噪声现在生产柱塞泵的厂家很多，进口件和国产件结构不尽相同，每一台泵都应严格按照其出厂使用说明书使用。在维修泵时，首先应该检查泵在系统中的安装、使用是否得当，便于及时查出损坏原因，消除隐患，保证系统正常工作。已修复的液压泵应通过一定的检测设备检测后才能使用。如不具备检测条件，也应在系统中反复调试，使其能正常工作。1．液压泵输出流量不足或不输出油液柱塞泵漏油主要有以下原因：(1)主轴油封损坏或轴有缺陷、划痕；(2)内部泄漏过大，造成油封处压力增大，而将油封损伤或冲出；(3)泄油管过细过长，使密封处漏油；(4)泵的外接油管。

柱塞运动到下止点，进油结束。2．中位时排油量不为零4．输出压力异常(2)管道内液流产生的噪声1．液压泵输出流量不足或不输出油液进油过程变量式轴向柱塞泵的斜盘倾角为零时称为中位，此时泵的输出流量应为零。但有时会出现中位偏离调整机构中点的现象，在中点时仍有流量输出。其原因是控制器的位置偏离、松动或损伤，需要重新调零、紧固或更换。泵的角度维持力不够、倾斜角耳轴磨损也会产生这种现象。柱塞泵漏油主要有以下原因：现在生产柱塞泵的厂家很多，进口件和国产件结构不尽相同，每一台泵都应严格按照其出厂使用说明书使用。在维修泵时，首先应该检查泵在系统中的安装、使用是否得当，便于及时查出损坏原因，消除隐患，保证系统正常。 推动伺服活塞向下移动，伺服阀的上阀口打开，变量壳体下腔的压力油经变量活塞中的通油孔进入变量壳体上腔，由于上腔面积大于下腔，液压力推动活塞向下运动，带动销轴使变量头绕钢球中心旋转，改变变量头的倾斜角(增大)。
