    摘要： An automatic, hydraulically actuated, sequencing valve 25 for use with a pair of hydraulic actuators (e.g. double acting hydraulic cylinders) includes a valve body 40 having a cylindrical bore 45 therein. Cam members 49 and 50 at either end of the bore are engaged by pins 62, 63 on the ends of a cylindrical spool 47, thereby rotating the spool 30 degrees each time it engages one of the cam members. A third cam member 78 incorporated into the spool alternately locks open one of a pair of check valves 57, 59 as said spool is pressure shifted between the two bore cam members. The third cam member operates a locking system which permits only one of the two hydraulic cylinders to operate at a time and in sequence.

    摘要翻译： 用于与一对液压致动器（例如双作用液压缸）一起使用的自动液压致动排序阀25包括其中具有圆柱孔45的阀体40。 孔的任一端的凸轮构件49和50通过在圆柱形卷轴47的端部上的销62,63接合，从而每当其与凸轮构件中的一个接合时，使卷轴旋转30度。 当所述线轴在两个孔凸轮构件之间压力移动时，并入到阀芯中的第三凸轮构件78交替地锁定一对止回阀57,59中的一个。 第三凸轮构件操作一个锁定系统，其允许两个液压缸中只有一个在一个时间和顺序上操作。
