Description

Technical Field

[0001] The utility model relates to the technical field of remote oil suction diffraction pumps, in particular to a multifunctional diffraction pump integrating remote and near-end oil suction. Background Art

[0002] At present, more and more fuel vehicles use narrow and long fuel tanks and hump fuel tanks. For these two types of fuel tanks, the fuel pump assembly not only needs to transport the fuel at the near end to the engine, but also needs to transport the fuel at the far end of the tank to the near end.

[0003] Under the existing technology, the fuel pump assembly usually adopts two diffraction pump structures. One diffraction pump is assembled on the bracket to transport fuel from the proximal end of the fuel tank, and the other diffraction pump is installed on the fuel storage barrel to transport fuel from the distal end to the proximal end. Such a structure requires the fuel storage barrel to be designed with a fixed diffraction pump structure and a fixed distal oil pipe structure. This will lead to a series of problems such as a more complex structure of the fuel storage barrel, difficulties in mold design and manufacturing, a shortened mold life, increased production costs, and poor versatility of the fuel pump assembly.
