Patent ID: 7874818

Claim:
An electric motor and fuel pump assembly comprising: a housing having a pair of generally opposed ends; an electric motor disposed within the housing and having an armature with a shaft with an axis of rotation and an axial commutator adjacent one end thereof and adjacent one end of the housing with the shaft extending axially outward of the commutator; a fuel pump disposed within the housing adjacent one of the ends of the housing, and operably connected to the armature to be driven by the electric motor; a brush carrier disposed within the housing adjacent the commutator and having a brush guide to slidably receive an electrically conductive and axially elongate brush with the brush being radially spaced from the shaft with the axis of the brush generally parallel to the axis of rotation of the armature shaft; the electrically conductive and axially elongate brush slidably received in the brush guide and radially spaced from and axially overlapping the shaft, wherein the brush has generally opposed ends with one end contacting the commutator, wherein the axis of the brush is generally parallel to the axis of rotation of the armature shaft; a spring associated with the brush and bearing on another end of its associated brush to yieldably bias its associated brush into contact with the commutator and the spring having a body radially spaced from the brush and axially adjacent the brush and radially spaced from the armature shaft; an outlet cover overlying the brush and spring and including an end with a female fuel outlet port radially spaced from the armature shaft and extending into the cover and axially overlapping the brush and spring and laterally spaced from the brush; and the spring comprises a torsional spring having a coiled body with an axis disposed transversely to the axis of rotation of the armature shaft and the coiled body is axially spaced from and does not axially overlap the brush.
