  • Electric motor fuel pump having a reduced length
    Patent number: 7874818
    Abstract: An electric motor and fuel pump assembly with a housing having generally opposed ends with an electric motor within the housing having an armature with an axial commutator adjacent one end of the armature and one end of the housing. A fuel pump is positioned adjacent another end of the housing and the armature and is operably connected to the armature for being driven by the electric motor. A carrier within the housing has guides slidably receiving axially elongate brushes disposed generally parallel to the armature axis with ends contacting the commutator. Each brush is biased generally axially into contact with the commutator by a torsional spring with a coiled body having an axis generally transverse to the axis of the armature to decrease the overall axial length of the pump assembly.
