Novel fuel bunker with axial limiting and compressing function

The invention relates to a novel fuel bunker with the axial limiting and compressing function. The novel fuel bunker is composed of a soft fuel tank which is compressible in the length direction and corresponding limiting devices which are additionally arranged. The novel fuel bunker comprises an fuel bunker shell (1), the front compacting limiting device (2), the rear compacting limiting device (3), a driving system (24) and the compressible soft fuel tank (5), wherein the compressible soft fuel tank (5) is located in the fuel bunker shell (1); the front compacting limiting device (2) and therear compacting limiting device (3) are compacted at the two ends of the compressible soft fuel tank (5); and when fuel in the compressible soft fuel tank (5) is reduced, the front compacting limiting device (2) and the rear compacting limiting device (3) are driven by the driving system (24) to synchronously move face to face, and the gravity center of the fuel in the compressible soft fuel tank(5) does not change.
