近年来.在液压传动方面,一些外国公司研制、生产了不少具有高级技术性能的各种结构的动力油缸,并取得了专利。 内腔被横隔板分为两室的单向作用油缸的结构是众所周知的,弹性活塞位于第一室,其活塞杆从缸体伸出,并与所传动的机械相连;自由浮动的差动活塞位于与液力能源沟通的第二室。两室通过中央管道彼此相
In recent years, in terms of hydraulic transmission, some foreign companies have developed and produced many power cylinders of various structures with advanced technical properties and obtained patents. The construction of a unidirectionally acting cylinder in which the interior space is divided into two compartments by a diaphragm is well known. The resilient piston is located in the first chamber and the piston rod extends from the cylinder and is connected to the driven machine. The free-floating differential The piston is located in the second room communicating with hydraulic energy. Two rooms each other through the central pipeline
