提供了一种用于气动轴定位系统（100）的机构和过程。 根据各种示例，气动轴定位系统包括烟火阀（137），其被配置成控制从加压气体源（135）进入压力室（109,111）的气体流。 压力室包括可滑动地联接到压力室的第一活塞（113,115,117,119）。 当来自加压气体源的气体填充压力室时，活塞构造成通过压力室滑动并迫使轴（103）进入预定位置。

They pneumatic shaft positioning system mechanisms and processes are provided. According to various examples, the pneumatic shaft positioning system comprises a technique valve Pyro configured to control the flow of gas into the pressure chamber from the pressurized gas source. The pressure chamber comprises a first piston that is slidably coupled to the pressure chamber. When the gas from the pressurized gas source to fill the pressure chamber, the piston is configured to slip through the pressure chamber to force the shaft to a predetermined position.
