Reverser/zh-hant

逆轉機是一種控制裝置，通常透過操縱桿進行操作，用於切換動力車輛的行駛方向：前進、後退、或空檔；空檔通常會使車輪與動力總成完全分離。在車輛行駛中不應該操作逆轉機，以免導致動力總成徹底失效。也因此，逆轉機通常必須在油門或動力軔機完全放鬆之後才能進行操作。

On steam engines, the equivalent of the reverser is called cutoff. It is a bit more complex in that it determines the steam intake duration per cylinder cycle.
