  • Fuel supply apparatus
    Patent number: 7806109
    Abstract: A fuel pump unit includes a fuel pump which is driven by a motor, a secondary filter case placed to surround the fuel pump and contains a filter, a reserve cup which houses the fuel pump and the secondary filter case, and a pump controller which drivingly controls the fuel pump. A shielding material is provided in the reserve cup to shield electrical noise generated by the fuel pump. The shielding material is grounded. The pump controller includes a pump drive circuit which is provided with an electric filter.
    Type: Grant
