    • A pneumatic actuator system includes an actuator unit (A) with at least one piston-cylinder type actuator (14) intended for crust breaking operations at electrolytic alumina reduction baths and comprising a working piston and two 5 end position responsive valves (5, 6), and a control unit (B) with a monostable distribution valve (3) having flow restrictions (3b, 3c) for directing pressure air to either side of the actuator piston, and a bistable monitoring valve (2) for letting through or blocking pressure air supply to the distribution valve (3) depending on the position of the forward end position 10 senring valve (6), and a monostable reset valve (1) shifted by the start signal from a stable open position letting through pressure air to one of the control ports of the monitoring valve (2) and an unstable closed position blocking air supply to that monitoring valve control port. Independently of the duration of the start signal the actuator piston will ålways return automatically to its 15 retracted rear end position as the piston reaches its forward end position at a completed working stroke, i.e. should the start signal be shorter the piston will return before performing a complete working stroke. 20 (Fig. 2)
    • 气动致动器系统包括致动器单元(A),其具有用于在电解氧化铝还原浴处进行结壳断裂操作的至少一个活塞 - 缸式致动器(14),并包括工作活塞和两个5个端部位置响应阀(5,6) 和具有用于将压力空气引导到致动器活塞的任一侧的流量限制(3b,3c)的单稳态分配阀(3)的控制单元(B)和用于通过或阻塞压力的双稳态监视阀(2) 取决于前端位置10旋转阀(6)的位置和分配阀(3)的空气供应,以及通过启动信号从稳定的打开位置转移到压力空气中的单稳态复位阀(1) 监控阀(2)的控制端口和不稳定的关闭位置阻止向监控阀控制端口供气。 独立于启动信号的持续时间,当活塞在完成的工作行程时到达其前端位置时,即,如果起动信号较短,则执行器活塞将在执行之前立即返回,自动返回到其缩回的后端位置 完成工作中风。 20(图2)
