摘要：Fuel tanks, on the top side of which a vent line of a flexible material is arranged,are already k微信壁纸
nown. In order to prevent compression of the vent line, the vent line is laid in a recess formed in the fuel tank. This leads to a reduction in cross ction and to the formation of cavities in which air pockets form even when the tank is completely full. The
福州医保reduction in cross ction leads to strength problems particularly in the ca of a fuel tank which consists of two opposing chambers which are connected to one another via an overflow pipe. The new vent line is intended to avoid the said disadvantages. This is achieved in that the vent line (1) is made from a dimensionally stable material and is connected at one of its ends by way of a fixed bearing (28) and at its opposite, other end via a movable bearing (20) to the surface of the fuel tank (1). The vent line is particularly suitable for plastic fuel tanks.
