典型实例 (1) 空气起动马达 (2) 进气口 (3) 控制阀 (4) 起动马达电磁阀 | |
当接通压缩空气主供气时，压缩空气首先供给到控制阀。 压缩空气主供气被控制阀封住。 控制阀允许一部分控制气压流过控制阀，流到起动马达电磁阀。
当起动发动机时，常闭起动马达电磁阀被触发，电磁阀将开启与其相连的阀。 此阀使得控制气压能够流到空气起动马达内部的活塞的背后。
压缩空气驱动涡轮旋转。 转子使用减速齿轮来带动小齿轮的驱动轴旋转，小齿轮带动飞轮旋转，继而盘车起动发动机。
当发动机开始运转时，飞轮就开始转得比小齿轮快。 小齿轮驱动轴的实际使得小齿轮能够移离飞轮。 这会防止空气起动马达、小齿轮和飞轮齿圈发生损坏。
当发动机控制模块感测到盘车终止转速时，起动马达电磁阀 (4) 就会被停止通电。 控制阀关闭，这样就切断了通向起动马达的压缩空气主供气。
