In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0026] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium.

[0028] With the rapid development of aerospace, military equipment, and specialized vehicles, the requirements for fuel storage devices are becoming increasingly stringent. While traditional metal fuel tanks offer high strength, they suffer from disadvantages such as heavy weight, high cost, corrosion susceptibility, and inconvenient maintenance. Flexible fuel bags, due to their lightweight, foldable, and adaptable nature, are becoming an increasingly important fuel storage solution.
[0029] Currently, common flexible fuel bags on the market are primarily made of materials such as rubber and nylon, with a multi-layer composite structure. However, in actual use, these composite fuel bags are prone to wrinkling and deformation due to severe vibration or impact, affecting the stability of fuel supply.
[0030] Reference Figures 1 to 5 The present application provides a novel rubber oil injection and discharge flexible composite device, comprising a bag body 100, an oil passage and a support assembly 300.
[0031] The bag body 100 is an annular structure, and an opening 110 is provided on one side of the bag body 100. The oil passage is provided inside the bag body 100, and the oil passage extends along the length direction of the bag body 100. The end face of the bag body 100 is provided with a connecting hole connected to the oil passage, and the oil passage is connected to the inside of the bag body 100. An elastic hard pipe 200 is passed through the oil passage, and a through hole 220 is provided on the elastic hard pipe 200. A plurality of support assemblies 300 are provided, and each support assembly 300 is arranged at intervals along the length direction of the bag body 100. The support assembly 300 includes a plurality of arc-shaped support springs 310, and each support spring 310 is arranged at intervals on the inner side of the inner circle of the bag body 100.
[0032] During use, the new rubber oil injection and discharge flexible composite device is set in the hard oil tank, and the connection hole on the end face of the bag body 100 is connected to the engine. The new rubber oil injection and discharge flexible composite device is squeezed by the gas pressure between the new rubber oil injection and discharge flexible composite device and the hard oil tank. During the squeezing process, the fuel inside the bag body 100 will flow out from the oil passage into the engine to supply oil to the engine. The elastic hard pipe 200 plays a supporting role to ensure stable oil supply, and the support component 300 plays a role in supporting the inner circle of the bag body 100 to prevent the new rubber oil injection and discharge flexible composite device from wrinkling and retaining too much oil after being flattened. This new rubber oil injection and discharge flexible composite device provides a separate supply channel for fuel because it has an oil passage through which the elastic hard pipe 200 is passed. At the same time, the support component 300 can effectively prevent serious wrinkles and deformation inside the bag body 100, thereby ensuring the stability of fuel supply.
[0033] In some embodiments, the end of the elastic hard pipe 200 is connected to the connection hole of the end surface of the bag body 100 through the flange 210. The flange 210 is provided to facilitate the connection and fixation of the bag body 100 with other equipment.
[0034] In some embodiments, the body of the elastic hard pipe 200 is a spirally extended elastic plate structure, which provides the oil passage with elasticity and better support.
[0035] In some embodiments, the body of the elastic hard pipe 200 is covered with through holes 200. The through holes 200 ensure that the oil flows stably in the oil passage.
[0036] In some embodiments, connecting pipes 230 for connecting to the flange 210 are provided at both ends of the elastic hard pipe 200 to facilitate installation of the flange 210 .
[0037] In some embodiments, the support spring 310 is connected to the bag body 100 via an aramid tape 400 .
[0038] In some embodiments, a strap set 111 is provided on opposite sides of the inner side of the opening 110 of the bag body 100. After the novel rubber oil injection and discharge flexible composite device is put on the corresponding equipment, the strap sets 111 on opposite sides are connected by ropes, thereby tightening the opening 110 of the bag body 100 and making the bag body 100 tightly wrap the equipment.
[0039] In some embodiments, multiple oil passages are provided. This can improve oil supply efficiency. For example, in this application, two oil passages are provided.
[0040] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.
[0041] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
