    Abstract: The device comprises, on one hand, a degassing tube (5) having one end (5a) which opens onto the upper inner part of the tank, markedly lower down than an upper wall (2) of the tank, and, on the other hand, a pipe (8) connecting the inner part to the exterior of the tank through a valve (V) carried by the wall (2), the valve being of the normally open ball (19) and float (10) type, the float (10) extending sufficiently downwardly to be raised by the fuel (7) when the latter reaches said end (5a), the lower end (10B) of the float (10) being lower than the end (5a) of the tube (5), and means are provided to ensure that this raising closes the valve (V) in a partly opened state. This device ensures simultaneously a permanent communication of the inside of the tank (1) with the atmosphere, a guarantee of an integrated expansion volume in the tank, and the prevention of flow of fuel in the event of an overturning of the vehicle.

    Abstract translation: 一方面,该装置包括脱气管(5),该脱气管(5)具有一个端部(5a),该端部开口于罐的上部内部,比罐的上壁(2)明显地低,并且在另一端 通过由壁(2)承载的阀(V)连接罐的内部与外部的管(8),阀是常开球(19)和浮子(10)型, 浮子(10)充分向下延伸,以便当燃料(7)到达所述端部(5a)时由所述燃料(7)升高,所述浮子(10)的下端(10B)低于所述管的端部(5a) 5),并且提供装置以确保该升高在部分打开的状态下关闭阀(V)。 该装置确保同时使罐(1)的内部与大气永久地通信,保证罐中的集成膨胀容积的保证,以及在车辆翻倒的情况下防止燃料流动。
