工程液压缸中的缓冲可调节流阀安装在油缸的端部,使活塞运动到达行程终端时,起缓冲作用,消除或减轻冲击。缓冲结构按设计手册中介绍的有以下三种形式,如图1所示。它们各有特点。图1(a)示节流行程可调有限,较宜用于小型油缸的设计;图1(b)示和图1 The buffer in the engineering cylinder is adjustable. The flow control valve is mounted on the end of the cylinder to cushion the piston when it reaches the end of its stroke, eliminating or reducing the impact. The buffer structure according to the design manual described in the following three forms, shown in Figure 1. They have their own characteristics. Figure 1 (a) shows a limited adjustable throttling schedule, preferably for the design of small tanks; Figure 1 (b) and Figure 1
