A cap for a fuel tank of a vehicle may be arranged during use to close a communication path between the fuel tank of the vehicle and the outside environment and provided internally with a through conduit, which is typically closed by a flow control element, which may elastically move at least as the pressure value inside the fuel tank increases, therefore, air is allowed to temporarily escape from the oil tank until the pressure value is reduced. The cover includes a first partition plate and a second partition plate for closing the conduit. The first bulkhead substantially has a shape inclined toward a bottom surface arranged at a lowest vertical height during use and is formed with at least one opening arranged at a vertical height higher than a vertical height of the bottom surface during use. A blocking element is free to move within the conduit between the bulkheads and is generally located on the bottom surface during use, the blocking element being provided with a profile adapted to automatically close an aperture provided in the second bulkhead upon selective displacement of the element toward the second bulkhead.
一种用于车辆油箱的盖,该盖在使用期间可以布置成封闭车辆的油箱与外部环境之间的连通路径并且在内部设置有贯通的管道,该管道通常由流动控制元件封闭,该流动控制元件可以至少随着油箱内部的压力值增大而弹性地移动,以便允许空气从油箱暂时逸出直到压力值减小。盖包括用于封闭管道的第一隔板和第二隔板。第一隔板基本上具有朝向底表面倾斜的形状并且形成有至少一个开口,该底表面在使用期间布置在最低竖直高度处,该开口在使用期间布置在比底表面的竖直高度更高的竖直高度处。阻挡元件在管道内在隔板之间自由移动并且在使用期间通常位于底表面上,阻挡元件设置有适于在元件朝向第二隔板的选择性的移位之后自动封闭设置在第二隔板中的孔的轮廓。
