The invention provides a ventilation device and a rail vehicle, the ventilation device is installed on an oil tank of an internal combustion engine power or hybrid power rail vehicle, the ventilation device comprises a first pipeline, a second pipeline, a third pipeline and a switching assembly, the first pipeline is installed above the oil tank and communicates with the oil tank, and the second pipeline is installed above the oil tank and communicates with the third pipeline; one end of the second pipeline is connected with the other end of the first pipeline, and the other end extends downwards along the height direction; one end of the third pipeline is connected with the other end of the first pipeline, and the other end extends upwards along the height direction; the switching assembly is installed among the first pipeline, the second pipeline and the third pipeline and is suitable for enabling the first pipeline to communicate with the second pipeline under the condition that the railway vehicle runs normally so as to balance the internal pressure and the external pressure of the oil tank. And under the condition that the railway vehicle accelerates or decelerates, the fuel oil rising along the first pipeline in the oil tank pokes the switching assembly, so that the first pipeline is communicated with the third pipeline.
本公开提供了一种通气装置和轨道车辆,该通气装置安装于内燃机动力或混合动力的轨道车辆的油箱上,该通气装置包括第一管道、第二管道、第三管道以及切换组件,第一管道安装在油箱上方,并与油箱连通,第二管道一端与第一管道的另一端连接,另一端沿高度方向向下延伸;第三管道一端与第一管道的另一端连接,另一端沿高度方向向上延伸;切换组件安装于第一管道、第二管道和第三管道之间,适用于在轨道车辆正常运行的情况下,使第一管道与第二管道连通,以平衡油箱的内外压力;以及在轨道车辆加速或减速的情况下,油箱内的沿第一管道上升的燃油拨动切换组件,使第一管道与第三管道连通。
