Description

technical field

[0001] The invention relates to a horizontal fuel pump assembly, in particular to an arch bridge type cantilever pump core fixing structure fuel pump assembly. Background technique

[0002] At present, the existing horizontal fuel pump assembly mainly includes an upper cover and an oil storage box. The upper cover and the oil storage box are connected by a spring guide rod, and a fuel pump is installed in the oil storage box. , due to the impact of road conditions, bumps inevitably lead to vibrations. Therefore, in order to reduce the vibration force borne by the fuel pump, prevent damage to the fuel pump, and ensure the working stability of the fuel pump, the existing horizontal fuel pump assembly is fixed on the fuel pump. When pumping, a vibration damping pad is basically installed under the fuel pump in the oil storage box to buffer the vibration force of the fuel pump. Using this damping structure is not only inconvenient for production and assembly, but...
