Problems solved by technology

[0003] For the existing fuel pump module, use rubber material to reduce the vibration of the fuel pump, so that the vibration of the fuel pump cannot be transmitted to the fuel pump module to reduce noise
[0004] However, the reduction of vibration using rubber can reduce the noise of the fuel pump because it reduces the frequency vibration of the entire fuel pump. Noise caused by abnormal vibrations such as

Abstract

Provided is a fuel pump module for a vehicle in which a fuel pump, which is a vibration body, is physically coupled to an intank filter, a primary filter, and the like, which are other components of the fuel pump module, to have increased mass, such that unique harmonic acceleration of the fuel pump is reduced, a unique vibration area of the fuel pump or the fuel pump module is changed, and harmonic vibration of the fuel pump is thus positioned at the unique vibration area of the fuel pump or the fuel pump module, thereby making it possible to remove noise generated in a fuel tank due to abnormal vibration of the fuel pump module.

Description

technical field [0001] The present invention relates to a vehicle fuel pump module. More specifically, it relates to a fuel pump module for a vehicle that eliminates noise of a fuel tank due to vibration of the fuel pump module by increasing the mass of the fuel pump module. Background technique [0002] When power is applied to components of the fuel pump module, the fuel pump sends the fuel in the fuel tank to the engine. The fuel pump to which power is applied generates resonance acceleration at a constant cycle according to the revolutions per minute (RPM). This usually occurs as the noise of the fuel pump module, especially when the resonant acceleration of the fuel pump is in the natural vibration frequency range of the fuel pump module or the fuel pump, abnormal vibration and noise are generated. [0003] As far as the existing fuel pump module is concerned, the rubber material is used to reduce the vibration of the fuel pump, so that the vibration of the fuel pump ...
