The invention relates to a liner section (10) for a bulkhead chamber (34) of a fuel tank structure, the liner section comprising: a liner section base body (12) wherein the liner section base body (12) is adapted to float on fuel in the fuel tank structure; at least one liner segment sidewall (14), wherein the at least one liner segment sidewall extends from the liner segment base body (12); a plurality of drain holes (16), where the plurality of drain holes (16) are arranged in the liner segment base body (12), and where the plurality of drain holes (16) are adapted to provide a bidirectional fluid connection from an upper side (18) of the liner segment (10) to a bottom side (20) of the liner segment (10) facing a fuel tank structure; at least one valve (22) arranged in the cut-out (30) of the liner section (10) wherein the at least one valve (22) is adapted to provide a one-way fluid connection from the bottom side (20) of the liner section (10) to the upper side (18) of the liner section (10) such that the one-way fluid connection is prevented in the opposite direction, the fuel tank structure is configured such that the remaining portion of fuel within the fuel tank structure is reduced by ensuring fuel flow from below the liner section of the adjacent bulkhead chamber to the liner section (10) required to extend safe operation of the fuel pump in the fuel tank structure.

    本发明涉及一种用于燃料箱结构的隔框室(34)的衬里段(10),该衬里段包括:衬里段基体(12),其中衬里段基体(12)适于浮置在燃料箱结构中的燃料上;至少一个衬里段侧壁(14),其中该至少一个衬里段侧壁从衬里段基体(12)延伸;多个排放孔(16),其中该多个排放孔(16)布置在衬里段基体(12)中,并且其中多个排放孔(16)适于提供从衬里段(10)的上侧(18)到衬里段(10)的面向燃料箱结构的底侧(20)的双向流体连接;至少一个阀(22),该至少一个阀布置在衬里段(10)的切口(30)中,其中该至少一个阀(22)适于提供从衬里段(10)的底侧(20)到衬里段(10)的上侧(18)的单向流体连接,使得单向流体连接在相反方向上被阻止,使得通过确保从相邻隔框室的衬里段下方到延长燃料箱结构中的燃料泵安全操作所需的衬里段(10)的燃料流动,减少了燃料箱结构内的燃料的剩余部分。
