溢流阀控制油路的特点通过调整弹簧的压力控制进油路的压力，保证进口压力恒定，p2＝0通过调整弹簧的压力控制出油口的压力，保证出口压力p2稳定直控式－通过调定调压弹簧的压力控制进油路压力；夜控式－由单独油路控制压力出油口情况出油口与油箱相连出油口与减压回路相连出油口与工作回路相连泄漏形式内泄式外泄式外泄式进油口状态及压力值常态常闭（原始状态）常开（原始状态）常闭（原始状态）工作状态进出油口相通，进油口压力为调整压力进油口压力低于出油口压力，出油口压力稳定在调定值上进出油口相通，进油口压力允许继续升高联接方式并联串联实现顺序动作式串联作卸荷阀用时并联功用定压、溢流或安全作用限压、稳压、保压减压、稳压不控制系统的压力，只利用系统的压力变化控制油路的通断进油腔压力p1控制阀芯移动出油腔压力p2控制阀芯移动进油腔压力p1控制阀芯移动

德国REXROTH力士乐产品在中国的重点项目：

1；2010年上海世博会期间，博世力士乐为德国馆内互动式“魔术球”设计驱动与线性传动方案并提供技术支持。“魔术球”循环次数可达一百万次，吸引了成千上万的参观者。博世力士乐巧妙的解决方案保证了运行安全性和稳定性，满足了“魔力球”不断运动的需求。
2；博世力士乐为中国国家大剧院提供了较先进的舞台控制系统。戏剧院主舞台的15个升降台可以每秒0.5米的速度快速精确地完成6.8米的升降行程，并能将其产生的噪音严格控制在65分贝以内。
3；在武汉长江隧道的建设施工过程中，一台直径达11.38米的盾构机依靠72台配置特殊密封系统的博世力士乐特制油缸，在艰难的施工条件下始终保持正常运转。
4；2007年，在中国**高楼——上海环球金融中心即将封之际，混凝土单泵垂直泵送高度打破了当时的世界记录。这一混凝土输送系统上安装的博世力士乐轴向柱塞泵保证了系统运行所需的压力，确保工程项目顺利完成。
5；挑战海拔4，000米极限的青藏铁路，其施工条件极为严苛。配备有力士乐液压系统的建筑机械，**了工程按时保质完成
6；在跨海大桥东海大桥的建设中，海上打桩作业是较大的挑战。“洋山号”打桩船就此担起重任，其全船液压及电气控制系统均由博世力士乐提供
