The invention relates to the technical field of hydraulic control, in particular to a sequential expansion cylinder and a combination thereof. The sequential expansion cylinder and the combination thereof have stable hydraulic system pressure and high operating efficiency. The expansion cylinder and the combination focus on eliminating the technical defects existing in the action or structure of asequential expansion cylinder in the prior art, and a special-structure floating seat type one-way valve arranged at the bottom of a cylinder body and a stroke valve arranged on a piston rod head arearranged to stably and reliably achieve sequential expansion control on the multi-stage cylinder. The sequential expansion cylinder and the combination have the characteristics that the structure iscompact and reasonable, the hydraulic system pressure is stable, and the operating efficiency is high.

    一种顺序伸缩油缸及其组合。本发明涉及液压控制技术领域,尤其涉及一种顺序伸缩油缸及其组合。提供了一种液压系统压力稳定、运行效率高的一种顺序伸缩油缸及其组合。本发明着力消除了现有技术顺序伸缩油缸在动作上或结构上存在的技术缺陷,通过油缸体底部设置的这种特殊结构浮座式单向阀,及活塞杆头设置的行程阀,能稳定可靠的实现多级油缸的顺序伸缩控制。本发明具有结构紧凑合理、液压系统压力稳定、运行效率高等特点。
