用于液压轴的液压回路和液压轴
摘要：
本发明涉及一种用于多面式缸的液压回路。多面式缸的活塞具有两个拉回面和一个移出面。通过可摆转的液压机器，多面式缸的活塞可以移入和移出。设置有控制阀用于在活塞的快速动作与施力动作之间进行转换。其中，控制阀以这样的方式布置，即对于快速动作，第一拉回面和移出面可再生连接。此外，控制阀以这样的方式布置，即对于施力动作两个拉回面可以相互连接。此外，本发明还涉及一种设计成紧凑型结构单元的液压轴进行。在这里设置控制集成块，所述液压回路和液压机器布置在控制集成块内。然后多面式缸和液压机器的驱动单元法兰连接到控制集成块上。液压轴的凑型的结构单元可以形成封闭的液压循环。
摘要（英）：

The invention relates to a hydraulic circuit for a polyhedral cylinder. A piston of the polyhedral cylinder has two drawing back surfaces and a moving out surface. Through a rotatable hydraulic machine, the piston of the polyhedral cylinder can be moved in and out. A control valve is disposed for switching between rapid motion and force motion of the piston. The control valve is arranged in such a manner that for the rapid motion, a first drawing back surface and the moving out surface can be in regeneration connection, and in addition, the convel valve is arranged in such a manner that for force action the two drawing back surfaces are connected with one another. Additionally, the invention also relates to performance on a hydraulic axle which is designed into a compact structural unit. A control intergration block is disposed herein. The hydraulic circuit and the hydraulic machine are arranged in the control integration block, and then the polyhedral cylinder and a driving unit of the hydraulic machine are in flange connection to the control integration block. The compact structural unit of the hydraulic axle can form enclosed hydraulic circulation.
