    • There is provided structure of a brush of a fuel pump for a vehicle in which the brush is formed of two kinds of different materials unlike a typical brush which is formed of only one material, more particularly, a high resistance material is used at one side portion only of the brush, and the same efficiency is ensured as that of the typical brush formed of low resistance material only, by suppressing the spark generation even in use of ethanol and low grade fuels and suppressing the spark generated in high current fuel pump and minimizing the abrasion of the structure due to decrease of spark generation, thereby ensuring the durability and the reliability and improving the EMI characters due to decrease of spark noise of the fuel pump.
    • 提供一种用于车辆的燃料泵的刷子的结构,其中刷子由仅由一种材料形成的典型的刷子形成的两种不同的材料形成,更具体地,在一侧使用高电阻材料 并且与仅由低电阻材料形成的典型的刷子相同的效率,即使在使用乙醇和低级燃料的同时也抑制了火花发生,并且抑制了在大电流燃料泵中产生的火花,并且 由于火花发生的减少,使结构的磨损最小化,从而确保了由于燃料泵的火花噪声的降低引起的耐久性和可靠性以及改善的EMI特性。
