空气切断阀由油压促动。 空气切断阀使用一个移动板来阻止空气进入发动机。 发动机因通往燃烧室的空气供给受到限制而停机。 空气切断阀将在以下情况下开动:

  • 按下紧急停机按钮。

  • 空气切断阀启用。

  • 发生超速停机。

作为一种安全装置提供了手动释放按钮 (1),可以允许维修人员在开始维修前释放切断阀。 手动释放按钮不得用于在运转的发动机上释放切断阀。 所需拉力为 316 to 414 N (71 to 93 lb)

注: 客户可以装备一个开关来启用空气切断阀。

重新起动发动机前,必须手动复位空气切断阀。 要复位空气切断阀,使用扳手按照箭头所示的方向转动指示器上的六角螺母。 转动六角螺母,直到指示器 (2) 处于 OPEN(开启)位置。
